Quick answer
The label does not provide a complete list of expected side effects. Ginger can cause abdominal discomfort, heartburn, diarrhea and mouth/throat irritation in some people. Botanical extracts and piperine can also raise interaction questions.
Allergic reactions
Severe hives, lip/tongue/throat swelling, wheezing, fainting or breathing difficulty require urgent medical care.
Medication interactions
Ginger and piperine are reasonable ingredients to flag during a medication review. A pharmacist or clinician can evaluate the actual medicine list.
When to seek care
Sudden severe pain, major swelling, a hot red joint, fever, inability to bear weight, trauma or rapidly worsening symptoms should not be managed by simply adding a supplement.
