Discussion

Arivela viscosa seeds have a high oil content (26%), are rich in linoleic acid, and are eaten in India. The leaves and seeds have been used medicinally in Asia (southern China, Guam, India) for the eyes and intestines, and as a poultice for headaches and rheumatism (R. N. Chopra et al. 1986; N. D. Mandahar 2002). Records from New Jersey and Pennsylvania are based on non-persistent ballast plants from the late 1800s.
