Panax ginseng is considered to be safe when used for short durations of time at appropriate dosages. As a natural medicine, it has been used for over 2,000 years in the Asian continent and is widely viewed to improve the health of the user.
Its use is contraindicated in some individuals with certain medical conditions and it may interact with some commonly used drugs.
However, in the majority of cases there are no serious side effects for short-term oral use. The most commonly reported Panax ginseng side effect is insomnia, which is why it is best to avoid taking this stimulating herb late in the day.

Is Panax Ginseng Safe?
Panax Ginseng extract remains one of the most popular herbal supplements ever used. Its long history of use should be considered as a testament to the tolerability profile of this supplement. However, it can cause side effects such as insomnia and interactions with other herbal remedies and medications.
According to the Natural Medicines Database, Panax Ginseng is possibly safe, “when used orally and appropriately, short-term.” The recommended safe dosage is 100 – 500 mg daily, for up to eight weeks.
In some instances, larger dosages of 900 mg three times a day have been used for treating Erectile Dysfunction. In research trials for COPD and diabetes, dosages of between 3 – 8 g have been used daily. However, these larger dosages should not be used unless under the instruction of a qualified physician.
For use longer than 8 weeks, Panax Ginseng is rated as “possibly unsafe”. This is due to concerns about the potential hormone-like effects of the plant extract, which could cause negative effects if used for prolonged periods of time. The Natural Medicines Database recommends that patients should limit continuous use to less than 6 months.
