Histamine Scavenger is a unique formulation used to help the body clear itself of excess histamine. Histamine is a compound which is released by cells in response to injury and in allergic and inflammatory reactions, causing contraction of smooth muscle and dilation of capillaries. Histamine can be generated from acute or chronic inflammation and has many unpleasant downstream effects on the body. Gut dysbiosis can also generate histamine that further impairs digestion.
