ABSTRACT

Kidney diseases are a major problem of worldwide proportions and renal damage is very common

since kidney has the capacity to excrete toxic substances. A phytotherapeutic approach to modern

drug development can provide many invaluable drugs from traditional medicinal plants. Search for

pure photochemical as drugs is time consuming and expensive. Numerous plants and polyherbal

formulations are used for the treatment of renal diseases. However, in most of the severe cases, the

treatments are not satisfactory. Although experimental evaluations were carried out on a good number

of these plants and formulations, the studies were mostly incomplete and insufficient. The therapeutic

values were tested against a few chemicals-induced subclinical levels of kidney damages in rodents.

In this review some of the plants with their extract studied for protective effect in renal diseases were

summerised.

Keywords: Medicinal plants, nephroprotective agents, renal disorders.

INTRODUCTION

Drugs are a common source of acute

kidney injury. Compared with 30 years ago,

the average patient today is older, has more

comorbidity, and is exposed to more

diagnostic and therapeutic procedures with the

potential to harm kidney function. Drugs

shown to cause nephrotoxicity exert their toxic

effects by one or more common pathogenic

mechanisms.

Drug-induced nephrotoxicity tends to

be more common among certain patients and

in specific clinical situations. Therefore,

successful prevention requires knowledge of

pathogenic mechanisms of renal injury,

patient-related risk factors, drug-related risk

factors, and preemptive measures, coupled

with vigilance and early intervention. Some

patient-related risk factors for drug-induced

nephrotoxicity are age older than 60 years,

underlying renal insufficiency (e.g.,

glomerular filtration rate of less than 60 mL

per minute per 1.73 m2), volume depletion,

diabetes, heart failure, and sepsis. General

preventive measures include using alternative

non-nephrotoxic drugs whenever possible;

correcting risk factors, if possible; assessing

baseline renal function before initiation of

therapy, followed by adjusting the dosage;

monitoring renal function and vital signs

during therapy; and avoiding nephrotoxic drug

combinations. Nephrotoxicity is a poisonous

effect of some substances, both toxic

chemicals and medication (nephrotoxins are

chemicals displaying nephrotoxicity) on the

kidneys. A number of antibiotics including the

penicillins, cephalosporins, tetracyclines, as

well as aminoglycosides and sulfonamides, are

potential nephrotoxins. Aminoglycoside

nephrotoxicity is manifested functionally by

decreased urine concentrating capacity, tubular

proteinuria, lysosomal enzymuria, mild

glucosuria, decreased ammonium excretion

and lowering of glomerular filtration rate

(GFR). Approximately 8% to 26% of patients

who receive aminoglycosides for more than 7-

10 days develop mild renal impairment which

is almost always reversible 1-3.

DIFFERENT NEPHROTOXICITY

MECHANISM

Gentamicin induced toxicity

Gentamicin, a typical aminoglycoside

antibiotic is widely used in clinical practices

for the treatment of life threatening gram-

negnegative infections. This antibiotic

generally causes drug-induced dose-dependent

nephrotoxicity in 10-20% of therapeutic

courses. Gentamicin induced nephrotoxicity is

characterized by direct tubular necrosis,

without morphological changes in glomerular

structures. Gentamicin generates hydrogen

peroxide in rat renal cortex mitochondria and

can also enhance the generation of reactive

oxygen species (ROS). Abnormal production

of ROS may damage some macromolecules to

induce cellular injury and necrosis via several

mechanisms including peroxidation of

membrane lipids, protein denaturation and

DNA damage. The alteration in kidney

functions induced by lipid peroxidation is a

proximal event in the injury cascade of

gentamicin mediated nephrotoxicity.

Gentamicin also acts as an iron chelator and

the iron-gentamicin complex is a potent

catalyst of radical generation 4-5.

Cisplatin induced toxicity

Cisplatin (Cis diamine

dichloroplatinum II) is a highly effective

antineoplastic DNA alkylating agent used

against a wide variety of cancers. Although

higher doses of Cisplatin are more efficacious

for the treatment of cancer many reversible

and irreversible side effects including

nephrotoxicity, neurotoxicity, bone marrow

toxicity, gastrointestinal toxicity and

ototoxicity often limit its utility and

therapeutic profile. Primary targets of cisplatin

in kidney are proximal straight and distal

convoluted tubules where it accumulates and

promotes cellular damage, by multiple

mechanisms including oxidative stress, DNA

damage and apoptosis.

Adv J Pharm Life sci Res, 2014 2;2:24-40 www.ajplronline.org

Advanced Journal of Pharmacie and Life science Research 26

Several lines of evidence suggest the

role of ROS in the pathogenesis of

nephrotoxicity. Cisplatin induces free radical

production causing oxidative renal damage,

possibly due to depletion of non-enzymatic

and enzymatic antioxidant system 6.

Acetaminophen induced toxicity

Acetaminophen-induced liver necrosis

has been studied extensively, but the

extrahepatic manifestations of acetaminophen

toxicity are currently not described well in the

literature. Renal insufficiency occurs in

approximately 1-2% of patients with

acetaminophen overdose. The

pathophysiology of renal toxicity in

acetaminophen poisoning has been attributed

to cytochrome P-450 mixed function oxidase

isoenzymes present in the kidney, although

other mechanisms have been elucidated,

including the role of prostaglandin synthetase

and N-deacetylase enzymes. Paradoxically,

glutathione is considered an important element

in the detoxification of acetaminophen and its

metabolites; however, its conjugates have been

implicated in the formation of nephrotoxic

compounds.

Acetaminophen-induced renal failure

becomes evident after hepatotoxicity in most

cases, but can be differentiated from the

hepatorenal syndrome, which may complicate

fulminant hepatic failure. The role of N-

acetylcysteine therapy in the setting of

acetaminophen-induced renal failure is

unclear. This review will focus on the

pathophysiology, clinical features, and

management of renal insufficiency in

the setting of acute acetaminophen toxicity 7.

Aloe barbadensis

Aloe vera has been used for medicinal

purposes in several cultures for millennia:

Greece, Egypt, India, Mexico, Japan, and

China. The therapeutic claims made for Aloe

vera range over a broad list of conditions, as

do the pharmacological activities associated

with it. Here the protective effects of the

aqueous leaf extract of Aloe barbadensis

(AEAB) has studied on gentamicin and

Cisplatin-induced nephrotoxic Wistar rats. In

each model of nephrotoxicity, thirty adult male

Wistar rats were evenly divided into 5 groups.

Groups I and II served as untreated and model

controls, respectively while groups III-V were

the treatment groups which were pretreated

with 100-200 mg/kg bodyweight per day of

AEAB 1 h before each dose of the

nephrotoxicants. On the 8th day(in case of

gentamicin) and on 6th day(in case of

Cisplatin), blood samples for serum urea, total

protein and creatinine as well as some ions

like sodium, potassium, chloride and uric acid

while the rat kidneys for histology were

obtained under inhaled diethyl ether

anesthesia. In the gentamicin nephrotoxic rats,

100-200 mg/kg bodyweight per day

significantly attenuated elevations in the serum

creatinine, total protein and blood urea

nitrogen levels in dose related fashion and no

treatment related effect on uric acid and ions,

and attenuated the gentamicin-induced

tubulonephrosis. Similar effects were also

recorded in the Cisplatin model of acute renal

injury.

The nephroprotective effect of AEAB

could be due to the inherent antioxidant and

free-radical-scavenging principle(s) contained

in the extract.9 [Figure 1]

Vernonia cinerea

Vernonia cinerea less belonging to

family Asteraceae. Mainly it consists of 38%

fatty oil. plant contains β–amyrin acetate, β-

amyrinbenzoate; lupeol and its acetate, β-

sitosterol,stigmosterol,a-spinasterol, kcl and

also contains flavonoids,glycosides,tannins

and carbohydrates.

The different parts of vernonia cinerea

diabetic activity, anti-pyretic activity, anti-

bacterial activity, diuretic and anti-diuretic

activity, anti-inflammatory activity, free

radicals and No scavenging activity, Analgesic

activity. The alcoholic extracts of aerial parts

of vernonia cinerea has been examined for the

effect of petroleum ether, ethyl acetate on

cisplatin-induced nephrotoxicity at a dose of

6mg/kg, i.p. in albino rats. The alcoholic

extract showed pronounced curative activity

and the ethyl acetate extract has exhibited

good prophylactic activity and petroleum ether

extract showed moderate protection for both

curative and prophylactic models against

cisplatin-induced toxicity 10. [Figure 2].

Boerhaavia diffusa

The current study designed to

investigate the effects of pre-treatment of

aqueous extract of B. diffusa root (200 – 400

mg/kg/day) in repeated dose acetaminophen

nephrotoxic rats for 14 days. Administration of

acetaminophen to rats induced marked

detritions of renal function, characterized by a

significant increase in blood urea nitrogen

(BUN), serum creatinine (p < 0.01) and

injured the renal cells evident from increased

level of kidney malondialdehyde (MDA),

protein thiol (p < 0.01) along with depletion of

super oxide dismutase (SOD), catalase (CAT),

glutathione peroxidase (GPx) activities and

reduced glutathione (GSH) levels (p < 0.01),

however pre-treatment with B. diffusa extract

protected against these changes.

Histopathological changes showed that

acetaminophen caused significant structural

damages to kidneys like tubular necrosis,

degeneration of epithelial cells, glomerular

damage and congestion which was reversed

with B. diffusa. The results suggest that B.

diffusa has the potential in preventing the

acetaminophen-induced nephrotoxicity11.

Indigofera barberi

The entire plants including the flowers

of Indigofera barberi has been well-known in

treating jaundice and renal diseases. The

present study designed to evaluate the

nephroprotective effect of ethanol extract of

whole plant of I. barberi (Linn) in paracetamol

induced nephrotoxicity of albino rats. The

ethanol extract of I.barberi (250 mg and 500

mg/ kg body weight) was administered orally

ones for 14 days.

Nephrotoxicity was induced in rat by

administering single dose of paracetamol (750

mg/kg). The degree of nephroprotective

activity was measured by renal functional

parameters such as serum urea (UR), uric acid

(UA) and creatinine (CR).and hematological

profile was concluded that the ethanol extract

of I-barberi is an effective nephroprotective

agent 12. [Figure 4].

Pimpinella tirupatiensis

Pimpinella tirupatiensis (Apiaceae) is

a herbaceous medicinal plant used to treat

cough, stomach, liver problems, asthma, ulcer

and tooth ache in India and other Asian

countries. The aim of the present study is to

investigate the nephroprotective and

antioxidant activities of the ethanol extract of

P.tirupatiensis in two dose levels of 500mg/kg

& 750 mg/kg B/W respectively on APAP

induced toxicity in rats. Biochemical studies

show that there is an increase in the levels of

serum urea and creatinine along with an

increase in the body weight and reduction in

the levels of uric acid in APAP induced

groups. These values are retrieved

significantly by treatment with P.tirupatiensis

extracts at two different doses.. Apart from

these, histopathological changes also reveal

the protective nature of the P.tirupatiensis

extract against acetaminophen induced

necrotic damage of renal tissues. In

conclusion, these data suggest that the ethanol

extract of P.tirupatiensis can prevent renal

damage from APAP induced nephrotoxicity in

rats.13. [Figure 5].

Curcumin

We report the role of mitochondria in

the protective effects of curcumin, a well-

known direct and indirect antioxidant, against

the renal oxidant damage induced by the

hexavalent chromium [Cr(VI)] compound

potassium dichromate K2Cr2O7 in rats.

Curcumin was given daily by gavage using

three different schemes: (1) complete

treatment (100, 200, and 400 mg/kg bw 10

days before and 2 days after K(2)Cr(2)O(7)

injection), (2) pretreatment (400 mg/kg bw for

10 days before K2Cr2O7 injection), and (3)

posttreatment (400 mg/kg body weight 2 days

after K2Cr2O7 injection). Rats were sacrificed

48 h later after a single K2Cr2O7 injection (15

mg/kg, sc) to evaluate renal and mitochondrial

function and oxidant stress.

Curcumin treatment (schemes 1 and 2)

attenuated K2Cr2O7 -induced renal

dysfunction, histological damage, oxidant

stress, and the decrease in antioxidant enzyme

activity both in kidney tissue and in

mitochondria. Curcumin pretreatment

attenuated K2Cr2O7 induced mitochondrial

dysfunction (alterations in oxygen

consumption, ATP content, calcium retention,

and mitochondrial membrane potential and

decreased activity of complexes I, II, II-III,

and V) but was unable to modify renal and

mitochondrial Cr(VI) content or to chelate

chromium. Curcumin posttreatment was

unable to prevent K2Cr2O7 -induced renal

dysfunction. 14.

Aegle marmelos

Present investigation was carried out

to evaluate the Nephroprotective activity of an

aqueous extract of Leaves of Aegle marmelos

in Wistar rats. The aqueous extract of Aegle

marmelos leaves (AEAM) was administered at

three doses (250, 500, and 750 mg/kg.) to

wistar rats in Gentamicin (GM)-induced

nephrotoxicity model. The rats were pre-fed

experimental diets for 8 days and then

received GM (100 mg/kg body weight/day)

treatment for 8 days while still on diet. Serum

parameters, oxidative stress in rat kidney were

analyzed.

GM nephrotoxicity was recorded by

increased serum creatinine and blood urea

nitrogen level. GM increased MDA level

whereas decreased catalase, reduced

glutathione level, while AEAM significantly

reduced the elevated MDA levels and

increased GSH and catalase concentration.

GM increased serum creatinine, urea and

blood urea nitrogen level, while AEAM

reduced serum creatinine, urea and blood urea

nitrogen level in gentamicin toxicity indicating

a nephroprotective effect. 15. [Figure 6].

Figure 6: Showing Aegle marmelos Plant

Erucasati va

Mercuric chloride (HgCl2) is a well-known

nephrotoxic agent. Increasing number of

evidences suggest the role of oxidative stress

in HgCl2 induced nephrotoxicity.

Eruca sativa is widely used in folklore

medicines and has a good reputation as a

remedy of renal ailments. In the present study,

the antioxidant potential of ethanolic extract of

E. sativa seeds was determined and its

protective effect on HgCl2 induced renal

toxicity was investigated. The extract was

found to possess a potent antioxidant effect,

with a large amount of polyphenols and a high

reducing ability. HPLC analysis of the extract

revealed glucoerucin and flavonoids to be the

major antioxidants present in it. E. sativa

extract significantly scavenged several

reactive oxygen species (ROS) and reactive

nitrogen species (RNS). Feeding of the extract

to rats afforded a significant protection against

HgCl2 induced renal toxicity. Subcutaneous

Tectona grandis

In the present study, effect of

ethanolic extract of bark of Tectona grandis

Linn. (TG) was evaluated using alloxan

induced diabetes and associated renal

complication. The diabetes was induced by

administration of alloxan to the rats at the dose

of 140 mg/kg, i.p. TG was administered to

diabetic animals for six weeks and various

biochemical parameters in blood and urine

(plasma glucose, serum albumin, total protein,

and creatinine, urine total protein, urine

albumin), tissue parameters (cholesterol and

triglyceride in kidney homogenate) and %

change in body weight were evaluated along

with histopathological study.

In present study diabetic animals

treated with TG showed significant reduction

in the elevated level of plasma glucose

(p<0.01) when compared with diabetic control.

While considering renal parameters, diabetic

animals treated with TG showed significant

decrease in serum creatinine (p<0.05), urine

albumin and urine total protein levels (p<0.01)

and significant increase in serum albumin,

total protein and % change in body weight

(p<0.01) when compared with diabetic control.

Diabetic control showed significant increase in

total cholesterol and triglyceride accumulation

in kidney, while diabetic animals treated with

TG showed significant decrease in levels of

total cholesterol (p<0.01) and triglyceride

(p<0.05) in the kidney when compared with

diabetic control.

Diabetic control showed significant

mark of glomerulosclerosis and hyalinization

which occurs because of severe diabetic

condition (diabetic nephropathy). Diabetic

groups treated with TG showed absence of the

sclerotic lesions produced by diabetic

condition. 17. [Figure 8].

diabetic and hypoxic rats. Duration of

streptozotocin-induced diabetes was 4 months,

that of respiratoric hypoxia of the diabetic

group 20 min. The daily dose of 100 mg EG

b/kg body weight started 1 month after

induction of the diabetes. EG b reduced

diabetes-induced morphological alterations of

the kidney such as increase in volume of

glomeruli, capillary tufts, urinary space, and

thickening of Bowman's capsule basement

membrane.

Diabetically increased

immunostaining of interstitial collagens of

types I, III, and VI was diminished by the EGb

extract. EGb reduced the relative total SOD

activity from 163% in diabetic kidney to 46%.

Additional hypoxia-induced ultrastructural

damage was also diminished 18. [Figure 9].

Abutilon indicum

The present study reported that the

etanolic extract of Abutilon indicum scavenge

superoxide and hydroxyl radicals, resulting in

a reduction of lipid peroxidation. The purpose

of the present study was to evaluate EEAI’s

efficacy as a protective agent against cisplatin-

induced ototoxicity. Albino wistar rats were

used in this study and were divided into five

treatment groups: (1) animals administered 2%

v/v aqueous tween 80 solution (5ml/kg, p.o) –

control group (Group I), (2) animals

administered 2% v/v aqueous tween 80

solution (5ml/kg, p.o) + 6 mg/kg via the i.p

route of Cisplatin (Group II), (3) animals

received Cystone (5ml/kg, p.o) [Standard]

(Group III), (4) animals received 200 mg/kg

EEAI suspended in 2% v/v aqueous tween 80

solution, p.o + 6 mg/kg, i.p of cisplatin (Group

IV), (5) animals received 400 mg/kg EEAI

suspended in 2% v/v aqueous tween 80

solution, p.o 6 mg/kg, i.p of cisplatin (Group

V).

The protective effect of EEAI on

CDDP-induced nephrotoxicity was evaluated.

Nephrotoxicity was evaluated by means of

measurement of serum BUN and creatinine

and histopathological examination of the

kidney.

There were significant differences in

serum BUN and creatinine levels between

control Group and cisplatin treated Groups.

The result suggested that EEAI at 200 and

400mg/kg administered 7 days before cisplatin

treatment significantly prevented the increase

of serum creatinine, blood urea nitrogen, uric

acid, total proteins, total cholesterol, alkaline

phosphatase, and albumin concentrations and

markedly decreased cisplatin-induced renal

damage as confirmed by biochemical assays

and histopathological studies 19. [Figure 10].

Euphorbia neriifolia

The present study was conducted to

investigate the chemopreventive effects of

hydro-ethanolic extract of Euphorbia neriifolia

(EN) on N-nitrosodiethylamine (DENA)

induced renal cancer in male Swiss albino

mice. Animals were pretreated with EN extract

(150 and 400 mg/kg body weight; p.o) and

butylated hydroxyanisole (BHA) as a standard

(0.5% and 1% BHA p.o) both for two week

prior to the administration of single dose of

DENA (50 mg/kg body weight; p.o). Various

in vivo antioxidant biochemical parameters

like lipid peroxidation (LPO), superoxide

dismutase (SOD), and Catalase (CAT) were

evaluated to determine the reno-protective and

antioxidant activity of EN. DENA increased

oxidative stress through increase in LPO and

decrease in antioxidant enzymes (SOD, and

CAT).

The EN extract significantly restored

the antioxidant enzyme level in the kidney and

exhibited significant dose dependant

protective effect against DENA induced

nephrotoxicity, which can be mainly attributed

to the antioxidant property of the extract. This

study rationalized the ethno-medicinal use of

EN for protection against renal cancer 20.

Rubia cordifolia

This study investigated the protective

effect of the hydro-alcoholic extract of roots of

Rubia cordifolia Linn. (HARC) against

ethylene glycol induced urolithiasis and its

possible underlying mechanisms using male

Wistar albino rats.

Ethylene glycol feeding resulted in

hyperoxaluria, hypocalciuria as well as

increased renal excretion of phosphate.

Supplementation with HARC significantly

prevented change in urinary calcium, oxalate

and phosphate excretion dose-dependently.

The increased calcium and oxalate levels and

number of calcium oxalate crystals deposits in

the kidney tissue of calculogenic rats were

significantly reverted by HARC treatment.

The HARC supplementation also prevents the

impairment of renal functions.

Results Indicate that the HARC can protect

against ethylene glycol induced urolithiasis as

it reduced and prevented the growth of urinary

stones. Therefore, HARC is helpful to prevent

the recurrence of the disease as it showed its

effect on early stages of stone development.

The mechanism underlying this effect is

mediated possibly through an antioxidant,

nephroprotection and its effect on the urinary

concentration of stone-forming constituents

and risk factors 21. [Figure 12].

Aerva lanata

Aerva lanata is also called as

Pasanabheda, Chaya, Gorakhganja belongs to

the family Amaranthaceae. The Aerva lanata

plant is reported to have α-amyrin,

campesterol, β-sitosterol, its palmitate, chrysin

and flavonoid glucosides63. Canthin-6-one

and β-carboline alkaloids were isolated from

Aerva lanata. Four new alkaloids viz., aervine,

methylaervine, aervoside and aervolanine were

isolated. The plant was reported for various

activities such as diuretic, hepato protective,

antidiabetic, antimicrobial, anthelmintic and

demulcent activity. Aerva lanata also shows its

effect on cisplatin and gentamycin model of

acute renal failure.

The ethanolic extract of the entire

plant of Aerva lanata was studied for its

nephroprotective activity in cisplatin and

gentamicin induced acute renal injury in

albino rats of either sex. In the curative

regimen, the extract at dose levels of 75, 150

and 300 mg/kg showed dose-dependent

reduction in the elevated blood urea and serum

creatinine and normalized the

histopathological changes in tha cisplatin

model. In the gentamicin model the rats in the

preventive regimen also showed good

response to the ethanol extract at 300 mg/kg.

The results suggest that the ethanolic extract of

Aerva lanatapossesses marked

nephroprotective activity with minimal

toxicity and could offer a promising role in the

treatment of acute renal failure caused by

nephrotoxins like cisplatin and gentamicin 22,

The alcoholic extract of Craaeva

nurvala 250 and 500 mg/kg for 10 days

showed protective activity against cisplatin 5

mg/kg induced nephrotoxicicty. The results

suggested, that the alcoholic extract has

significantly altered the dysfunction of renal

proximal tubule cells by decreasing the

concentration of blood urea nitrogen,

creatinine, lipid peroxidation, glutathione and

catalase 24, 25. [Figure 14].

Orthosiphon stamineus

Orthosiphon stamineus Benth. is a

medicinal herb belonging to the family

Lamiaceae.

The methanolic extract of orthosiphon

stamineus benth was evaluated for its

nephroprotective activity using rat model.

Gentamycin is an extensively used

aminoglycoside antibiotic. It has been reported

to produce nephrotoxicity even at normal

therapeutic dose level. The drug was

administered intra peritonialy at a dose of

80mg/kg weight for 9 days. Histopathological

sections showed marked glomerular,

peritubular and blood vessel congestion. These

increased levels of serum creatinine, blood

urea, urinary protein and extent of renal

damage were decreased by the methanolic

extract of Orthosiphon stamineus at both dose

levels that is 100 and 200 mg/kg body weight

in rats 26. [Figure 15].

Aerva javanica

Aerva javanica Juss. ex Schult is

medicinal plant belonging to the family

Amaranthaceae. The aqueous extracts of

Aerva javanica roots were studied for the

scientific evaluation of nephroprotective

activity. Various parameters like body weight,

blood urea, serum creatinine, serum protein,

total protein, serum albumin, urine volume and

pH, tissue protein, GSH and TBARS level

were compared with controls on 16th day after

treatment.

The study concludes that cisplatin

injury was evidenced by the elevated

biochemical markers and histopathological

features of acute tubular necrosis. The aqueous

extract at the dose level of 400 mg/kg body

weight was found to normalize the elevated

biochemical markers and bring about a marked

recovery in kidneys as evidenced by using

microscopy 29. [Figure 17].

plants have been used in traditional Indian

medicine for various range of ailments. To

evaluate the possible potential,

nephroprotective and curative role of the

methanolic extract of Ficus religiosa L. Latex

was used against cisplatin (5mg/kg, i.p.)

induced Nephrotoxicity.

The blood was collected from the

retro-orbital sinus of rats and determined for

urea and creatinine levels in serum of each

group after then rats were sacrificed for

quantitative estimation of various enzymes and

ATPases content in kidney tissue. A single

dose of cisplatin induced shows the increased

levels of urea & creatinine in serum and it was

significantly recovered by 400mg/kg in

curative and protective groups. The enzyme

estimation in kidney tissue has found that

increased malondialdehyde and decreased

reduced glutathione (GSH).

CONCLUSION

From this study, it is clear that the

medicinal plants play a vital role against on

various diseases. Various herbal plants and

plants extracts have significant

nephroprotective activity in animal models.

The nephroprotective activity is probably due

to the presence of flavonoids in all few herbal

plants. The results of this study indicate that

extracts of leaves and plants extracts of some

medicinal plant have good potentials for use in

renal disease. The present review study give

evidential explore mechanism of action of

medicinal plants against experimentally

induced nephrotoxicity.

Hence the review study is concluded

that the herbal drug possesses

nephroprotective activity and it has been

proved by different animal models give many

links to develop the future trials.
