All of our herbal bath soaks are based in high quality, all natural, kosher, USP-grade epsom salts. We add a generous amount of various herbs, roots, resins, and herbal powders to the salts; then, the bath mixtures are infused with essential oils to enhance the magic as well as their scent. The power of our herbal salt soaks can be apprehended in various ways - by simply pouring them directly into a bath; by using a pot to brew some of the mixture into a tea, then pour that brew into a bath or onto oneself during a shower; or to scrub oneself directly with the herbs and salt during a shower. Our large size baths weigh over twice the amount as our small baths, with an appropriately scaling amount of plant matter!
