India, April 29 -- Beauty and wellness influencers have been swearing by a 'brand new' cure-all practice on YouTube and Instagram - potlis. This trend started after celebrity nutritionist Shweta Shah posted a series of DIY potlis for hair growth, PCOS and pain relief, and migraines. Several wellness brands also joined the bandwagon, launching artisanal poultice bags. This time-honoured Ayurvedic practice combines heat, pressure, and the medicinal qualities of herbs. "The rhythmic motion of the massage and the aroma of the herbs have a calming effect on the nervous system, making it effective for reducing stress and promoting relaxation," explains Dr Anjana Kalia, Ayurvedic expert and nutritionist at Bloom Clinix. Certified vaidya Chandan Swami, shares, "The two most traditional ingredients in Ayurvedic potli ingredients are crystal salt and carom seeds (ajwain)." These are particularly helpful for pain relief. "Other commonly used herbs include turmeric, neem, ashwagandha, ginger, and eucalyptus for their specific healing properties," adds Dr Kalia. Camphor potlis are recommended for travelling at high altitudes with low oxygen. While the use of medicinal Ayurveda may be controversial from an allopathic perspective, small-scale studies suggest that potli therapy can provide relief. "This is true for conditions such as osteoarthritis, frozen shoulder, and general muscular tension. However, large-scale, randomised controlled trials are limited," informs Dr Prashant Sinha, general physician at PSRI Hospital, adding, "The use of heat in any therapy, including potli, does help, which is why hot compresses are recommended for musculoskeletal pain." There is value in integrating potli therapy as a supportive or complementary treatment in certain cases. However, it should not replace primary medical treatments. Dr Sinha cautions, "People with circulatory issues, diabetes-related neuropathy, or open wounds should avoid such therapy unless medically cleared." Other risk factors include burns or irritation, especially in people with sensitive skin, or allergic reactions from some herbs....
