Prickly heat (sweat retention syndrome) is an increasingly common disorder of the sweat glands, which extend deep into the skin. If these get blocked near the surface, sweat that cannot escape forms little blisters. Itching and irritation will follow. Blood purifying herbs when used in conjunction with topical porducts can have a pronounced effect on the prevention of prickly heat.
Since prickly heat worsens during exposure to sun, the best form of treatment involves the use of blood purifying and detoxifying herbs such as nettle extracts together with an appropriate soothing topical cream.
