Chemo is a heavy indica developed in the 70s in Canada to treat patients suffering from cancer treatments, especially chemotherapy. Since then, it has managed to evolve quite a lot. It has a rather woody aroma that promotes relaxation and wellbeing. But the true value comes from its amazing medical effects and the fact that it can help you deal with sleeplessness and other similar issues. Its best known feature is its ability to lower anxiety, almost eliminate nausea and promote appetite.
