Vitamin C
Vitamin C is a virucide (antiviral). It can help to ease herpes-related symptoms naturally because it is a powerful immune booster. It also helps to regulate histamine in the body. Histamine is released in response to stress, inflammation, and infection and is known to trigger the herpes virus (and vice versa). Because of this, a vitamin C deficiency can cause more frequent and severe herpes breakouts, colds, and flu. However, avoiding taking typical vitamin C supplements containing ascorbic acid (especially in high doses) is essential when living with the herpes virus.
