«Many of the Chinese patents are for herbal treatments. One, filed by the Yunan Industrial Cannabis Sativa Co, refers to an application made from whole cannabis sativa seeds to make “functional food” designed to improve the human immune system. Another, by an inventor called Zhang Hongqi, is for a “Chinese medicinal preparation” for treating peptic ulcers. It uses an array of ingredients, including cannabis sativa seed. The filing says it has “significant therapeutic effectiveness and does not cause any adverse effect”.
There is also a patent filing from China for a treatment for constipation, which is made using fructus cannabis and other ingredients such as “immature bitter orange”, Chinese angelica and balloon flower. This, it is claimed, treats constipation’s root causes and symptoms resulting in “obvious curative effects”.
However, only one company in the world has developed cannabis-based drugs as medicines that have been recognised by regulators in the West following the long, costly process of clinical trials. GW Pharmaceuticals, based in Wiltshire, makes Sativex for the treatment of symptoms of multiple sclerosis and cancer pain, and Epidiolex for childhood epilepsy.»
