The Comfrey Cast is 100% pure Comfrey root powder - simply reconstitute the potent powder with water; apply to the injured area; allow adequate time to dry into a fruit leather-like cast; keep on for as long as possible; peel off to remove, wet & scrub, or allow to crackle dry off. The Salve is comprised of Comfrey  leaf, Root, Kauai Beeswax & Cold-pressed raw coconut oil, prepared for easy application - simply massage into the skin to deeply penetrate the injured areas for regeneration & revitalization. Lastly, but not least, Comfrey Hydrosol is steam distilled  Comfrey leaf that holds the liquid essence of the plant & its combined suspended oils. To apply: Mist the area generously & reapply as needed. For major injuries, I like to use all three interchangeably. The hydrosol & salve can also conveniently be used for daily maintenance & optimal body performance. Putting love into every batch, The Kauai Farmacy Team xoxoxo
