- Trumpet satinash (Syzygium claviflorum) is a member of the Myrtaceae family, which includes 4,500-5,000 species of evergreen trees or shrubs that are found in the Mediterranean region, sub-Saharan Africa, Madagascar, tropical and temperate Asia, Australia, the Pacific Islands, and tropical South America. Betulinic acid is the main constituent of trumpet satinash and is believed to be responsible for its effects.
- Betulinic acid may have antitumor activity. Betulinic acid derivatives may have antiretroviral activity. However, there is currently a lack of clinical evidence in support of the use of trumpet satinash for any condition.
