How does Birch work?

Birch leaves contain chemicals which increase water loss through the urine.

Are there safety concerns?

Birch seems to be safe for most adults. It can cause allergic reactions in some people. People who are sensitive to celery, wild carrot or mugwort are more likely to have an allergic reaction to birch.

Do not use birch if:
  • You are pregnant or breast-feeding.
  • You have high blood pressure.
  • You have allergies to celery, wild carrot, or mugwort.
