Trees standing serene; they bring to us the feeling of comfort and a connection with Mother Earth, as we delight under their glorious canopies, take in the fresh aroma of their needles, cones, berries, flowers, resins, and bark, and somehow have an instinctual knowledge that they possess the powers to heal and bring great vitality. Worldwide studies of traditional home remedy medicines have documented many stories of people using tree extracts as herbal remedies. Various Pinaceous and Cupressus species, including pine, juniper, and cedarwood, have been used to treat wounds and external inflammation for decades, and even centuries. Pine tar was used by the ancient Sumerians to treat skin infections. Juniper berries were crushed and applied to wounds to reduce infection. In addition, Seminole Indians used Virginia cedarwood to treat rheumatism.
Modern studies look to back up the traditional claims of our ancestors who used extracts from various tree species topically on wounds and for inflammation. There have been a few in vivo (animal) and in vitro (in a lab / dish) studies on essential oils and extracts of these plants with impressive results. More research, and human trials are certainly needed. A list of research is listed below.
Instructions: In a crock pot, cook the olive oil, beeswax, and shea butter on low until it melts. Then, stir in the pink salt and ground oats. Finally, turn off the heat and stir in the essential oils. Pour immediately into container(s) with sealing lid(s). Wait to seal the lids until cooled. Apply salve topically to affected area. Discontinue use if any irritation occurs.
Here are a few of the studies found. More research, and human studies are necessary.
