Safety & Contraindications
Class 2b, 2d.“Hazards and/or side effects not known for proper therapeutic dosages”. Perhaps erring on the side of caution, Reichert cautions that ginger may raise the blood pressure, may amplify blood-thinning drug activities, and might be contraindicated in pregnancy. Contraindicated in childhood fevers and gallstones. Patients with gallstones should consult a practitioner before taking ginger. The Lawrence Review says overdoses may cause cardiac arrhythmias and CNS depression. Large doses possibly gastroirritant, causing a significant increase in exfoliation of gastric surface epithelial cells in human volunteers. Due to ginger’s strong antiaggregant activity, experts recommend it not be used by people with blood clotting disorders. Many chemotherapy patients experience periods when their blood platelet counts drop dramatically. Doctors will warn patients to avoid aspirin when their platelet counts are low. They feel that patients should also avoid ginger when their platelet count drops, while continuing use of ginger for patients with normal platelet counts. Less conservatively, Commission E reports rhizome should not be used for vomiting in pregnancy. Lininger et al. adds heartburn as a rare side effect. “A doctor should be informed if ginger is used before surgery to counteract possible postanesthesia nausea”.
