Hot salt pot compression is a process of postpartum care in Thai traditional medicine. Research studies or clinical trials on Hot Salt Pot Compression have indicated that the process can effectively support postpartum recovery, relieve aching pain and reduce waist size. The main ingredients of Hot Salt Pot Compression are seven herbs: Curcuma comosa, Zingiber montanum, Curcuma aromatica, Curcuma aeruginosa, camphor, sea salt and Crinum asiaticum. To date there have been no reviews of these herbs.  Therefore, this article aims to provide information on the ingredients which are related to anti-inflammation and relieving pain by reviewing secondary data. The reviews indicate that C. comosa, Z. montanum, C. aromatica, C. aeruginosa, C. camphora and C. asiaticum decrease inflammation on in vitro and in vivo studies by inhibiting inflammatory mediators (i.e. nitric oxide, prostaglandin E2 and cyclooxyganse-2) and relieving inflammation and pain in the rat model. In addition, C. comosa rhizome decreases uterine contraction in rats. In a clinical study, Z. montanum rhizome cream and oil reduce muscle pain in patients with muscle strain, myofascial pain syndrome and pain after exercise. The leaves of C. asiaticum are used in this process to wrap the Tha-Non pot; and there is research evidence showing that C. asiaticum leaves that have been dry-heated at 50 ºC for 30 minutes have the highest amount of active compound (lycorine) for anti-inflammation – the amount being higher than in fresh leaves. Thus, the results are consistent with the usage of C. asiaticum leaves in Hot Salt Pot Compression because the leaves are heated in Tha-Non pot before using with postpartum women. But there has been no report on the effect of sea salt on inflammatory reduction. In conclusion, Hot Salt Pot Compression can relieve uterine pain, muscle pain and inflammatory edema through two pathways: heating from sea salt and anti-inflammatory and pain-relieving properties of the herbal constituents. However, we suggest that future studies should be undertaken to investigate anti-inflammatory activities of C. comosa, C. aromatica, C. aeruginosa, C. camphora and C. asiaticum in a topical form in clinical trials to obtain basic data for developing herbal remedies for postpartum women in the future.
