Medicinal uses<br />
The Acorus calamus is used to treat diarrhoea (Shoba & Thomas, 2001). It is also<br />
used as an expectorant, carminative, antispasmodic and nervine sedative (Van Wyk<br />
et al., 1997; Padmaja et al., 2002).<br />
Data from ethnobotanical survey<br />
Its stem is ground, mixed with cold water, and the person with sores has to drink a<br />
quarter <strong>of</strong> a cup <strong>of</strong> the mixture three times a day (Zondo, 2007, pers. comm.).<br />
Chemical content<br />
Essential oils are found in the leaves, rhizomes and roots. Tannins are found in the<br />
rhizomes and roots; and ascorbic acid is found in the leaves and rhizomes. Known<br />
compounds from the plant include acorin, choline essence containing asarone,<br />
eugenol, pinene, cetylic acid, palmitic acid and vitamin B1 (Hutchings et al. 1996).<br />
Sesquiterpenes (acorenone) were also detected in this plant (Padmaja et al. 2002).<br />
Essential oil contains numerous monoterpenoids e.g. Camphene, p-cymene, linalool.<br />
Toxicity is ascribed to β-asarone, a phenyl propanoid (Van Wyk et al., 1997).<br />
