Rocky Mountain Oils’ CBD balm for pain relief includes Colloidal Gold, a natural solution made by suspending gold nanoparticles in de-ionized water. There are approximately 0.01-0.2 mg of gold per every 1 ml of water. Although research into the efficacy of Colloidal Gold is ongoing, it has been used for many decades in holistic healing. Colloidal Gold is said to relieve inflammation, treat and prevent damage caused by oxidative stress (free radicals), and promote faster healing times for injuries.
