Panax Ginseng Root Extract Side Effects

Panax ginseng, also known as Asian or Chinese ginseng, is an herb typically used for issues such as fatigue, erectile dysfunction and infertility. It is available in many forms including capsules, tinctures and teas. While Panax ginseng use generally poses a low chance of side effects, there have been some cases of side effects, especially when it is combined with stimulants or medications.

Over-stimulation

Panax ginseng is used for fatigue because it can work as a stimulant. Unfortunately, this stimulating property can cause side effects such as nervousness, hypertension, excitation and insomnia. Decreased concentration has been reported with long-term use, according to MD Anderson Cancer Center. For this reason, Panax ginseng is typically used for short periods of four to eight weeks. Tachycardia, an abnormally rapid heartbeat, can also result from the use of Panax ginseng. Taking Panax ginseng in combination with caffeine or other stimulants increases the chance of side effects due to over-stimulation. It is not recommended to take Panax ginseng in combination with heart or blood pressure medication as it can influence the effects of these drugs.

Hormone Issues for Women

Panax ginseng may have estrogen-like effects. Therefore, it may increase the risk of cancer growth in women with breast cancer. The estrogen-like effects of panax ginseng may also cause breast tenderness and vaginal bleeding. Panax ginseng is not recommended for those who are pregnant or breastfeeding or for those with breast cancer.

Low Blood Sugar

Panax ginseng can cause a decrease in blood sugar. According to the National Center for Complementary and Alternative Medicine, diabetes patients should use caution when taking Asian ginseng. It may interfere with blood-sugar medications as well as some herbs, such as fenugreek, that also lower blood sugar.

Blood Thinning

Another side effect of Panax ginseng is the thinning effect it can have on the blood. For this reason, The University of Maryland Medical Center recommends that patients discontinue the use of Asian ginseng for at least seven days prior to any surgeries, as it may increase the risk of bleeding during the procedure. Panax ginseng can also change the effects of warfarin and other blood thinners so those taking these medications should avoid it.

Increase in Mania

Panax ginseng may potentially cause an increase in the chance of manic episodes. This side effect is especially likely if Panax ginseng is combined with certain anti-depressants such as monoamine oxidase inhibitors (MAOIs). However, according to Sloan-Kettering Memorial Cancer Center, at least one case has been reported in which a patient with no previous mental illness exhibited manic symptoms after using 250 mg of Panax ginseng three times a day.
