Medicinal Uses

While extensive research exists for common species like Malpighia emarginata (acerola cherry), information specifically detailing the traditional or modern medicinal uses of Malpighia infestissima is limited in the provided search results. 

Malpighia infestissima has been identified as a recognized medicinal herb and adaptogen in general terms, but specific applications and scientific data are scarce. The plant is native to the U.S. Virgin Islands and is present in herbaria collections, but those records do not detail its uses.
