Puur Hotspot can be used for acute allergic reactions to insects and mites, or a hypersensitive reaction to plants and trees. The Urtica dioica (large nettle) in Hotspot is used for skin problems that look like irritation caused by nettles. A diluted extract of Ledum palustre (Wild Rosemary) is known for its effect against the results of insect bites, such as allergic skin reactions. This product reduces itching.
