Cytokinetic study of uninfected agarwood branch ethanolic extract on breast cancer cells

Breast cancer is the most common malignancy in women with more than 500,000 global death toll annually. Evidences from ethnopharmaceutical practices showed that Aquilaria spp. from Thymelaeceae family has been used traditionally as treatment of a wide range of disorders. However, scientific evidence...
