Hello. CBN (cannabinol) is a cannabinoid that is produced from the oxidation of THC. I haven’t come across any scientific studies regarding the effects of CBN and cysts. CBN can be used as a sleep-aid for people suffering from insomnia. It has anti-inflammatory and analgesic properties, as well as anti-bacterial properties. CBN can stimulate the appetite and control the growth of cancer cells, and may help people suffering with glaucoma. CBN is a fairly new cannabinoid being studied and requires more research.
