The paper reports effect of different concentrations (1%, 2.5%, 5% & 10%) of water-extracts ofOcimum sanctum (Tulsi) on Chara braunii. The plant body becomes healthy with normal photosynthesis at lower concentration while toxic effects are evident in higher concentrations. Percentage value of mitotic cell division increases at lower concentration, however, there is a decrease at higher concentration. These values are directly proportional to the concentration and duration of treatment. Higher doses inhibit survival patterns. The medicinal extracts induce karyological aberrations and their frequency increases with increasing concentration during the treatment.
