Tetradenia riparia (Hochst.) N. E. Br.
- Common Name: Nutmeg Bush, Mochasma
- Family: Lamiaceae Lindl.
- Country of Origin: South Africa - Natal, Transvaal
- Description: [syn. Iboza riparia (Hochst.) N.E. Br.]
Stout dioecious herb, 3-6 feet tall, white-pubescent, aromatic; leaves broadly ovate, 4-6 inches long, to 5 inches wide, slightly to deeply crenate, petioled; panicle mostly 8-15 inches long; calyx to 1/16 inch long, corolla unequally 4-5 lobed, to 3/16 inch long, white.
- Uses: Medicinal: Moderate antimalarial activity of the leaf essential oil against two strains of Plasmodium falciparum has been reported 7.
The diterpene diol 8 (14), 15-sandaracopimaradiene-7α,18-diol has been shown to possess papaverine-like antispasmodic activity on methacholine, histamine and barium chloride-induced contractions of guinea pig ileum as well as on noradrenaline-induced contractions of rabbit aorta 3.
Leaf extracts (80% ethanol), tested for antimicrobial and antiviral activity, inhibited the growth of Staphylococcus aureus, Candida albicans, Mycobacterium smegmatis, Microsporum canis, Trichophyton mentagrophytes and Bacillus subtilis.
No antiviral activity against Coxsackie virus, poliovirus (unspecified), measles virus and Semliki-Forest virus was demonstrated in these studies8, 9. Some of the observed antimicrobial activity has been attributed to the presence of diterpenes10, .
