Huwa San as plant regenerating product
• Orozco-Cardines and Ryan (1999) concludedthat, hydrogen peroxide is generated in response to wounding, and can be detected atwound sites within 1 hr after wounding
• The response is systemic and maximazies atabout 4-6 hrs in wounded leaves, and thendeclines

Huwa San TR 50 as plant protectionproduct
Webber and Sandtner (2007)The answer of authors for the anecdotal reports
Is the hydrogen peroxide plant stimulator or plant protection product?
In authors opiniongrowth stimulus of hydrogen peroxide, applied as
watering solutions, may be a result of the decreasing orelimination plant pathogens in the soil, rather than itserving as a direct stimulus to the plant (nasturtium)
