Vitamin C lowers histamine levels

Lower the histamine level with natural medicine - vitamin C infusion supported

The working group of Professor Dr. med. Martin Raithel at the University Clinic Erlangen recently investigated whether vitamin C infusions can lower increased histamine levels. Histamine is an endogenous messenger substance, the concentration of which increases in the blood and tissue during allergic reactions, infections and inflammations and which is responsible for many unpleasant symptoms. Since these diseases are often associated with a vitamin C deficiency [1-3], Dr. med. Alexander Hagel and colleagues asked 89 patients with allergies and infections whether a single infusion with the drug Pascorbin® can lower the histamine blood level. To do this, they determined the histamine blood levels before and after the infusion of 7.5 g of vitamin C in 19 patients with allergies and 70 patients with infections.

As expected, the mean histamine levels were significantly higher in patients with allergies than in patients with infections. In allergy sufferers, the histamine levels could be almost halved by the single infusion (Fig. 1).

The initial values ​​in patients with infections were significantly lower, some were even in the normal range, and were reduced by an average of 23.3%.

It is interesting to note that the reduction effect of vitamin C is related to the initial concentration of histamine: the higher the initial histamine values, the more pronounced the reduction effect of vitamin C. no significant changes.

In this study, only the histamine level, but not the symptoms of high histamine levels, was determined or queried. Nevertheless, doctors suspect that the therapeutic benefit of vitamin C infusions, which is often observed in diseases with excessively high histamine levels, is closely related to the histamine reduction.
