What to know
These are herbal supplements, not treatments. For each one, the human research is limited or mixed. Herbs can interact with medicines, so check before you combine them with anything prescribed.
Who should check first
- Blood thinners or surgery coming up: ginkgo, turmeric and cayenne can affect clotting. Speak to your doctor first.
- Liver conditions: do not take turmeric curcumin or green tea extract without your doctor's advice. Stop and see your doctor if you get yellowing of the skin or eyes, dark urine or nausea.
- Epilepsy: do not take ginkgo.
- Pregnant or breastfeeding: avoid all of these at supplement doses.
