Unexpected improvement of hyperhidrosis with cannabidiol:A 31-year-old man with treatment resistant hyperhidrosis was successfully treated with cannabis. He suffered from the disease for about 20 years and had tried all available standard treatment without relevant success. Treatment with cannabis flowers at a centre for cannabis medicine in Steinheim, Germany, effectively stopped excessive sweating, and the patient was able to lead a normal life.
The author concluded from the case report and a literature review: “THC shows anticholinergic effects, which can be used for the therapy of primary or secondary hyperhidrosis. In individual cases, CBD could also be helpful.” Primary hyperhidrosis generally begins between the ages of 14-25 years and is usually restricted to certain areas of the body, mainly axillae, soles of the feet, palms and face. Generalized sweating indicates secondary hyperhidrosis, for example due to cancer.
