dichotoma. Mixed and pounded, the expressed juice strained and mixed with lemon extract; taken three times daily.
• Antibacterial: A methanol extract of leaves, flowers, stems and barks, hexane and ethyl acetate extracts of stems/bark showed mild inhibition of Bacillus subtilis growth. (2)
• Anticonvulsant: Study evaluated the anticonvulsant activity of hydroalcoholic extracts of leaves and sepals and its fractions against PTZ, MES, STR, Picrotoxin induced convulsions at different dose levels. Results showed dose-dependent effects which may have potential in the control of grandmal and petit mal epilepsy. (3)
• Antitumor: Study evaluated the antitumor and antioxidant activity of Mussaenda philippica against MCF-7 and Caco2 cell lines induced breast and colon cancer in mice. (4)
• Diuretic: Study evaluated the diuretic activity of flowers of Mussaenda philippica var. Donya Luz. Results showed the crude extract of possess potential diuretic activity which could be further explored in the treatment of hypertension. (5)
