Mushrooms as therapeutic agentsemail this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Mushrooms have been known for their nutritional and culinary values and used as medicines and tonics by humans for ages. In modern terms, they can be considered as functional foods which can provide health benefits beyond the traditional nutrients. There are monographs that cover the medicinal and healing properties of some individual traditional mushrooms. There has been a recent upsurge of interest in mushrooms not only as a health food which is rich in protein but also as a source of biologically active compounds of medicinal value which include complementary medicine/dietary supplements for anticancer, antiviral, hepat...

Capsicum species, Solanaceae, have been used for centuries as food additives by populations of different regions of the world. Capsaicin (trans-methyl-N-vainillyl-nonenamide) is the main pungent compound extracted from the red hot pepper fruit (Capsicum spp.). The capsaicin content was determined by means of a HPLC method. The results showed that Capsicum chacoense Hunz., contains similar amounts of capsaicin (13.9 mg/100 g of dry fruit) in comparison with Capsicum baccatum L. (12.6 mg/100 g) and Capsicum annum L. (10.1 mg/100 g). Dichloromethane (CH2Cl2) and ethanol (EtOH) extracts of C. chacoense elicited a 46% and 38 % ...
