Natural therapeutics. Soothing, purifying, and relaxing. The original formula with powdered mustard seed, eucalyptus, rosemary, wintergreen and thyme. Dr. Singha's aromatic bath formula has been widely used in England for 40 years with excellent results. Traditionally, mustard is renowned for its stimulating, cleansing and rejuvenating qualities. The warmth of the mustard assists in opening the pores of your skin helping you to sweat our impurities. Dr Shyam Singha, well - known master acupuncturist, osteopath and naturopath, recommended his ayurvedic formula as an aid in relieving many ailments, including stress, muscle and joint soreness, congestion, skin conditions, periodic tensions, sleeplessness, and as a perfect complement to any purification and tissue cleansing program. Pure grade essential oils leave your skin feeling soothed and refreshed. A full - body or foot massage with Dr. Singha's mustard rub following a mustard bath (or at any time) is highly recommended.
