How does Aspen work?

Aspen contains a chemical that is very similar to aspirin. This chemical, known as salicin, may help reduce swelling (inflammation).

Are there safety concerns?

There isn't enough information to know if aspen is safe. Skin reactions, such as rashes, can occur if aspen comes in contact with the skin.

Don't drink alcohol while taking aspen. Alcohol can also increase the risk and severity of bleeding in the stomach and intestines.

Do not use aspen if:
  • You are pregnant or breast-feeding.
  • You are allergic to salicylates such as aspirin (Bayer).
  • You have an ulcer.
  • You have diabetes.
  • You have gout.
  • You have a blood disorder.
  • You have kidney or liver disease.
