According to classical homoeopathic texts, Ledum palustre or the Marsh tea is a First Aid cream for minor puncture wounds, stings, bites, and certain rheumatic conditions, relieved by cold applications.
However, homeopathy is not considered to be evidence based by the health authorities and regulators in Australia. This product has not been tested for efficacy and makes no therapeutic claims.
