Sarsaparilla root is traditionally used for detoxing, skin issues (psoriasis, eczema), joint pain (rheumatoid arthritis), and inflammation, with potential anti-cancer, antimicrobial, and immune-boosting properties . It's also used in clean beauty for soothing skin and was a historic root beer flavouring.

To use sarsaparilla root, brew a tea by simmering 1-2 teaspoons of dried root or powder in 2 cups of water for 10-15 minutes, then filter out the root pieces and serve.
