Christmas drinks
Christmas time brings with it the anticipa-
tion of home-made palate-arousing deli-
cacies and recipes, such as red sorrel
drink (from Hibiscus sabdariffa) and gin-
ger “beer”. For people living in this and
neighbouring countries, “ginger beer” is
made from rhizomes of ginger (Zingiber
officinale), which delivers a “burning”
pungent sensation on the tongue, as a
pleasant contrast to the sweetness of
“Christmas cake”. Some recipes allow
for the mixing of ginger beer with sorrel
drinks in splendid red-tinted concoctions
for Christmas time.
There are several recipes for ginger beer,
but the most important part making this
beverage is the selection of rhizomes
which are fresh and firm, and carrying a
strong spicy aroma. This characteristic
aroma of the plant is due to its volatile or
essential oil constituents.
The ginger plant is native to Southeast
Asia, and it has been used in traditional
Chinese and in Ayurvedic medicine for
hundreds of years. The herb was first
brought to the Caribbean region in the
16th century, aboard ships bringing inden-
tured labourers to the region – so it is
said. Today it is a cultivated species and it
can be processed into value-added prod-
ucts which are represented among the
nutraceuticals of international trade.
Rhizomes of ginger and its extracts have
been used effectively to treat nausea and
vomiting associated with motion sick-
ness; and its therapeutic constituents are
known to be mixtures of non-volatile
compounds called gingerols and shogaols,
which are also the pungent constituents of
the plant.
According to the 2006
book: “The Desktop Guide
to Complementary and Al-
ternative Medicine: An evi-
dence-based approach”, ed-
ited by Edzard Ernst, Max
Pittler and Barbara Wider,
the medicinal attributes of
ginger products have been
described inside official
European monographs for
ginger (Zingiberis rhizome)
since 1997, and they have
been approved by the US
Pharmacopoeia for inclu-
sion in the National Formulary.
Heeba and Abd-Elghany reported their
findings on pages 1076-1081 in Phy-
tomedicine, 2010, volume 17, that crude
extracts of ginger rhizomes are antioxi-
dant and anti-inflammatory in animal
models. But the evidence that the extracts
work in this way for humans is still to be
demonstrated in clinical trials published
in the scientific literature.

Zingiber officinale - ginger
the specific, descriptive epithet designat-
ing the species. Thus Allium sativum is
the scientific binomial of Garlic, Allium
being the genus, sativum being the spe-
cies. Thus the scientific name for Shado
beni became Eryngium foetidum, and was
confirmed in accordance with the 1930
International Code of Botanical Nomen-
clature.
And yet, over time it has been found in the
scientific literature that a single plant can
be given multiple scientific names. This is
the result of disagreements amongst the
botanists/taxonomists, and for other rea-
sons. Still these numerous scientific names
continue to cause confusion and problems
especially among the medicinal herbs.
Seeking to resolve such problems (and
other issues), the Royal Botanic Gardens,
Kew, and the Missouri Botanical Garden
(MOBOT) are currently conducting “The
Plant List” project. When completed “ The
Plant List” project should indicate which
scientific names are accepted as correct
and which are synonyms. Lindsay Stafford
has reported on this on-going project:“The
plant List: The First Comprehensive In-
ventory of Most Known Plant Species” in
the November 2010 issue of HerbalE-
Gram. In this report it was stated that “if
you search online resources for a medici-
nal or nutritional plant using just one of
the alternative scientific names of a spe-
cies, you might only find 20% of the infor-
mation about this species”.
People need to be alerted to these facts, so
that if they are interested in finding out
about any plant species, they need to
search using its alternative scientific
names (synonyms) as well.
Just suppose that you were trying to dis-
cover the facts about a medicinal plant;
where does it grow; does it have anti-
oxidant constituents; is it poisonous
or not, etc., etc.? You will need to
know the name(s) used for this herb
as recorded, if you are to find this
information in the scientific litera-
ture; and you will need to know the
scientific names used for it. So the
first problem arises, if you know
only the common (local vernacular)
name, but not the scientific (Latin
binomial name) of this herb.
The fact is that nearly every widely
used medicinal plant is known by
two or more common names. For
example, the local herb called Shado
beni in other countries is known by
other names, varying from Cilantro
and Bhandhaniya, to Fit Weed and
Spirit Weed and Sawtooth Corian-
der. The botanists (taxonomists) will
identify it everywhere by its scien-
tific name Eryngium foetidum L.,
and in this way any confusion is
minimized. Using the scientific name
will facilitate the on-line search for the
attributes of the plant. Of course the same
approaches will apply to any other plant
such as Garlic (Allium sativum).
Most of the oldest scientific names used
for plants are found in the 1753 book
“Species Plantarum” written by Carl Lin-
naeus, a Swedish botanist who is de-
scribed as the founder of taxonomy. It was
he who stated that: “If the names are un-
known, knowledge of the things also per-
ishes”.
In “Species Plantarum”, Linnaeus intro-
duced the binomial system of scientific
naming by combining the genus name and

“Developments in Botanical Dietary Sup-
plements Research from 1994 to Today”
was the title of a large one-day sympo-
sium held in Chicago, U.S.A. in March,
2010. It focused on the many possible
applications of plants to human health,
whilst embracing a broad number of sci-
entific disciplines, and it was widely per-
ceived as both an educational overview
and inspiring communication among
stakeholders. During its four sessions,
this meeting covered major aspects of
herbal medicinal product quality, regula-
tion and funding, the generation of clini-
cal evidence and other related issues. Ma-
jor sponsors of the event included two
agencies of the National Institutes of
Health, namely the Office of Dietary
Supplements (ODS) and the National
Center for Alternative and Complemen-
tary Medicine (NCCAM).
In the U.S., since the passage of the Die-
tary Supplements Health and Education
Act (“DSHEA”) in 1994, a herbal me-
dicinal product (“herb or other botani-
cal”) could be classified legally in the
market-place as a “dietary supplement”,
but not as a drug.
An editorial comment by Guido F. Pauli
was published in Fitoterapia journal is-
sue for January 2011, concerning the pro-
ceedings of the March symposium. His
introductory statements reflect the scien-
tist’s views, which are quoted as follows.
“Plants and mankind have evolved to-
gether throughout human history, and
throughout that history, mankind has
been utilizing plants for countless pur-
poses.” Ultimately, it is the (photo)
autotrophic character and ability of plants
to provide characteristic chemicals, i.e.,
phyto-constituents that serve as nutrients,
essential factors, therapeutics, and toxins,
which have given them an invaluable role
in human development. Accordingly, it
seems only natural that plants have al-
ways had therapeutic value...
“Historically they have been classified
very broadly as
either thera-
peutic or
toxic”.
Dr. Pauli also
states that
“Prior to 1994
and in the
U.S., only very
few plants in-
cluding ginger,
ephedra, and
aloe were considered to be over-the-
counter drugs. All other plant materi-
als were not classified at all. While they
could be sold, no health-related claims
were allowed unless they were approved
according to standards set by the US Food
and Drugs Administration (FDA), which
required significant scientific evidence for
the linkage between nutrient and disor-
der”.
Amongst its other achievements, the sym-
posium included up-to-date descriptions
of pre-clinical studies done on Noni
(Morinda citrifolia) fruits, and it empha-
sized the key role of placebo in the con-
duct of clinical trials using herbal medici-
nal products.
