Dr. Singha's Mustard Bath Soak is a warming, alkaline soak made from certified organic mustard seed powder and five pure essential oils to comfort muscles and gently cleanse skin.
This 28 oz jar contains a long-standing formula developed by Dr. Singha using organic mustard seed powder blended into a mild alkaline base. Designed for full baths or foot soaks, the mixture warms on contact with hot water, supports circulation, and leaves skin feeling softer without synthetic fragrances or common harsh additives. It’s been trusted by athletes, spa practitioners, and wellness-minded people for decades.
The mustard seed powder produces a natural warming sensation that can soothe tired muscles and promote surface circulation when combined with hot water. The aromatic essential oils also add a calming ritual element, making recovery feel deliberate and restorative.
The formula centers on certified organic mustard seed powder mixed into an alkaline base and combined with five pure essential oils: wintergreen, eucalyptus, rosemary, thyme, and gum benzoin. There are no artificial fragrances, parabens, talc, lanolin, or preservatives, which keeps the composition simple and focused.
Measure roughly 2 ounces per full bath in hot water and soak for about 20 minutes to experience the product’s warming and cleansing properties. For a foot soak, use a smaller basin and proportionately less product for a targeted treatment.
The formula avoids many common additives and synthetic fragrances, which reduces irritation risks for many people. However, mustard seed powder produces a warming sensation; perform a patch test if you have particularly reactive skin or known sensitivities to botanical oils.
Who is this for: Dr. Singha's Mustard Bath Soak is suited to active people, spa professionals, and anyone seeking a botanical, warming alternative to standard salt soaks. It’s ideal for those who prefer a cleaner ingredient list with natural essential oils and a time-tested recipe designed to support post-workout recovery, evening relaxation, or focused foot care.
