In-vitro cytotoxicity of various Siphonochilus aethiopicus (Schweinf.) B.L. Burtt extracts in combination with selected tableting excipients.

None of the excipients caused any significantly altered cellular effects, indicating little chance for physicochemical interactions. Aqueous extracts did not possess any cytotoxic properties. However, it is clear that organic extracts caused apoptotic and necrotic cell death.
