Timing

Willow bark contains salicin (aspirin-like) and should not be doubled up with NSAIDs.

Watch for: stomach pain, heartburn, nausea, black or bloody stools, decreased urination, ankle swelling, unusual weight gain (fluid retention), or elevated blood pressure. When to seek emergency help: Vomiting blood or material resembling coffee grounds, severe abdominal pain, chest pain, sudden shortness of breath, signs of allergic reaction (hives, facial swelling, difficulty breathing), or very dark urine with reduced output.
