Tinctures are generally high in potency and are intended to give patients a sugar-free, gluten-free, inhalation-free cannabis experience. Indica is sought after for its intensely relaxing effects. It may also help reduce nausea and pain and increase appetite. Great for chronic pain, sleep, nausea, and anxiety.
