Herbal medicine is a multi-billion dollar industry. In order to explore the potentials of medicinal plants, we have studied various plant extracts for various therapeutic applications such as anti-Inflammatory, antioxidant, anti-microbial, anti-diabetic and biopesticidal. In this paper, we will discuss the findings related to toxicity of these extracts based on cell-based toxicity assay. Out of 100 extracts tested, two extracts were found to be cytotoxic towards normal liver (WRL-68) and normal kidney (Vero) cell lines. These extracts exhibited median inhibitory concentration (lC50) of less than 10 µg/mI. Nevertheless, these two plants (Garcinia mangostana and Goniothalamus umbrosus) were also widely used in traditional herbal remedies. For example, G. man gostana is well known world wide for its antioxidant properties and anti-cancer effects of xanthones derived from its pericarp. Goniothalamus umbrosus, on the other hand, is a lesser known plant but common among traditional practitioners as a plant that is good for anti-cancer therapy. This paper attempts to discuss Issues related to toxicity of these plants.
