A tea made from the young shoots is used as a vermifuge by the Akan-Asanti of Ghana (Abbiw, 1990) as it is in Gabon (Raponda-Walker and Sillans, 1961). The Lombo from the Yangambi region of DR Congo, use the sap from the cut stems of this species, mixed with the bark Hua gabonii, Quassia africana and Pterocarpus soyauxii, to make a tea which is then used to treat dysentary (Staner and Boutique, 1937).

Uses The cane of this species is poor in quality. It is rather inflexible and prone to breaking. However, particularly in the absence of other species, O. mannii can be employed for coarse weaving. In the Congo, the stem epidermis is used by the Téké for tha manufacture of coarse baskets and local weaving. In Equatorial Guinea, the juvenile stems are sometimes used for weaving in the same manner as the young stems of E. macrocarpa, which they resemble; hence the same name for the juvenile form (Sunderland, 1998).

Vernacular names NIGERIA: iboh (Ekit): CAMEROON: madame (Trade/Pidgin); mo’ap (Balundu- Bima); edju (Bakundu-Balue); moa-echié (Denya) Uses This cane is not used commercially at all due to the poor quality of the cane (Sunderland pers. obs.; Morakinyo, 1994). It is rather weak, inflexible and rather prone to breakage on bending. However, the base of the leaf sheath is often used by the indigenous communities of SW Cameroon as a chew-stick (Sunderland unpubl. notes; Thomas et al., 1989; Sunderland & Tchouto, 1999). In Nigeria, the stem epidermis is often used for tying yams to their climbing poles (“yam-barns”) as it rots fairly quickly and does not constrict the developing climbing stems (Morakinyo, 1994).
