capsule
Conditions addressed
Suggested dosage
1–2 capsules daily with food, unless otherwise directed
Interactions & contraindications
May affect blood pressure
Watch for: Antihypertensive medications (ACE inhibitors, beta-blockers, calcium channel blockers, diuretics)
Combined use can push blood pressure too high or too low — monitor readings if you take blood pressure medication.
May thin the blood
Watch for: Anticoagulants (warfarin), antiplatelets (aspirin, clopidogrel), and other blood-thinning herbs or supplements (ginkgo, garlic, fish oil, vitamin E)
Combining blood-thinning substances can increase bleeding risk, including before surgery or dental work.
May affect immune activity
Watch for: Immunosuppressants (for transplant or autoimmune conditions)
Immune-stimulating herbs can work against immunosuppressive therapy.
May affect blood sugar
Watch for: Insulin and oral diabetes medications (metformin, sulfonylureas)
Additive blood-sugar-lowering effects can risk hypoglycemia — monitor glucose closely.
