Contraindications and Precautions
Some authors suggest that high-dose Siberian ginseng should be avoided by those with cardiovascular disease or hypertension (BP >80/90 mmHg). Others merely suggest a caution, as reports are largely unsubstantiated. As such, it is recommended that people with hypertension should be monitored if using high doses. A study in elderly people with hypertension over 8 weeks did not affect blood pressure control.
Due to possible effects on glycaemic control, care should betaken in people with diabetes until safety is established. Suspend use 1 week before major surgery.
Traditional contraindications include hormonal changes, excess energy states, fever, acute infection, concurrent use of other stimulants and prolonged use.
Insufficient reliable information is available, but the herb is not traditionally used in pregnancy.

• The herb is popular among athletes in the belief that endurance, performance and power may improve with its use, but clinical studies have produced inconsistent results.
