Histaminum hydrochloricum is a homeopathic remedy that is commonly used to treat allergies, asthma, bronchitis, and muscle and joint pain. It is made from histamine dihydrochloride.
Homeopathic medications are sold in pharmacies and are occasionally used together with standard medical treatments. Histaminum hydrochloricum should only be used under the guidance of a healthcare professional so that other treatment can be provided, if necessary, for potentially serious diseases.
Sufficient available evidence is lacking on the safety and effectiveness of histaminum hydrochloricum for any condition in humans.
