I am a HUGE Cannabis for medicine proponent (This does not mean that I am a stoner..). Topical pain relief oils help many of my friends and clients. It is very anti everything and pro health. Infused topical oil works on the nerves allowing two way communication where pain may be caused by only one channel being open due to immune system over activity because of injury or disease. Cannabinoids accomplish this by locking into your EXISTING CANNABINOID RECEPTORS and activating all sorts of healing functions within your systems. The combination of the Infused Oil AND Hemp Oil provides incredible cell wall strengthening. Hemp Oil from the seeds of the male plant contains over 80% of your essential fatty acids that you need and cannot produce yourself. Used on skin will heal any skin disorder, ingested will nourish your body and luricate it's systems. Forget Argan Oil, HEMP OIL! I have distilled Cannabis (extracted the essential oil and floral water) and used it topically for Acneic and Oily skin, it works wonders, there are absolutely NO CANNABINOIDS in the distillate only Aromatic Terpenes which play a vital role in the plants immune system. In fact the psychoactivity only comes once you decarboxylate the existing THCa and CBDa, in their raw form they are not psychoactive at all and play a very important role in the Immune system of Cannabis sativa. ALL parts of the plant can (and should) be used. Here is todays favorite article on the benefits of juicing it: http://www.medicaljane.com/2013/01/19/cannabis-the-foundation-of-health/
The picture is a close up of the trichomes (aka the resinoid glands that hold the aromatics and the cannabinoids; aka where the "magic" happens), which are first line of defense in the plant's immune system.
This is also a prime example of how the part of a plant you take can directly correlate to the part of your body you are looking to address. Mmmm..herbal nerdy food for thought..
