Allergies
When your liver functions properly, it produces antibodies which fight allergens. So, in case the liver’s work is decreased, your body stores the allergens. As a response, your brain produces histamine, which is a chemical that marks the allergens which should be eliminated. Also, you may want to know that in high level, this leads to allergy symptoms such as fogginess, headaches and itchiness.
Acne
The toxic buildup in your liver often leads to hormonal imbalances that can cause acne. If that acne is caused by the decreased liver function, it can not be treated externally.
