Immunostimulatory effect of methanol extract of Curculigo orchioides on immunosuppressed mice

The methanol extract of rhizomes of Curculigo orchioides Gaertn. (Amaryllidaceae) holds potential as a protective agent against cytotoxic drugs. The extract when studied on humoral and cell mediated immunity in normal, as well as cyclophosphamide-induced immunosuppressed mice produced an increase in humoral antibody (HA) titre, delayed type hypersensitivity (DTH) and levels of WBC in a dose dependent manner.
