Filipendula ulmaria In 1897, Felix Hoffmann created a synthetically altered version of salicin, derived from the species, which caused less digestive upset than pure salicylic acid. The new drug, formally acetylsalicylic acid, was named aspirin by Hoffmann's employer Bayer AG after the old botanical name for meadowsweet, "Spiraea ulmaria". This gave rise to the class of drugs known as non-steroidal anti-inflammatory drugs (NSAIDs). A natural black dye can be obtained from the roots by using a copper mordant. A tea made from "Filipendula ulmaria" flowers or leaves has been used in traditional Austrian herbal medicine for the treatment of rheumatism, gout, infections,
Moronic acid Moronic acid Moronic acid (3-oxoolean-18-en-28-oic acid) is a natural triterpene. Moronic acid can be extracted from "Rhus javanica", a sumac plant traditionally believed to hold medicinal applications. The molecule has also been extracted from Mistletoe ("Phoradendron reichenbachianum"). Bevirimat, a derivative of the related triterpenoid betulinic acid, is under development as an anti-HIV drug; however, moronic acid has shown better antiviral profiles "in vitro" than bevirimat. A particular moronic acid derivative showed potent anti-HIV activity with EC values of 0.0085 μM against NL4-3, 0.021 μM against PI-R (a multiple protease inhibitor resistant strain), and 0.13 μM against FHR-2 (an HIV strain
