Ginseng - Everything you need to know

It is recommended to limit the dosage of ginseng extract to one to two grams per day. An overdose can lead to possible consequences such as high blood pressure, insomnia and diarrhoea. People with diabetes or high blood pressure should consult their doctor before taking ginseng supplements. People taking blood-thinning medication should not use ginseng extracts, as ginsenosides can affect blood clotting (University of Rochester)

Rare side effects include stomach discomfort, nausea and mild diarrhoea. Please note that interactions may vary depending on the dosage form of a medicine. If you are taking ginseng root at the same time as anti-coagulant drugs called coumarin type, such as phenprocoumon or warfarin, the effect of these drugs may be weakened. There is the possibility of interactions with active substances such as sulfonylureas and their derivatives for treating diabetes mellitus. However, such interactions have not been studied so far.

Due to the oestrogen-like effects of ginseng, it is recommended that pregnant women, breastfeeding women, and children should not use it (MSD).

The effect of ginseng can vary from person to person and depends on various factors, such as the individual constitution, the dosage and the way it is taken. As a rule, however, it takes some time before the effect of ginseng becomes noticeable. When taken regularly over a longer period of time, often several weeks or even months, the positive effects of ginseng can gradually become noticeable. These include improved physical and mental performance, increased energy, increased resilience and improved stress tolerance. It is important to note that ginseng does not have an immediate effect, such as a stimulant. Instead, it is a gradual and long-term improvement in well-being and vitality. However, each person reacts individually; some people may notice the first positive effects sooner than others.

There is no hard and fast rule regarding what time of day ginseng should be taken, as it depends on various factors, such as individual tolerance and personal needs. Some people take ginseng in the morning to benefit from the energising effect during the day. Others prefer to take it in the afternoon to get an energy boost for the second half of the day. However, it is important to note that ginseng can have a stimulating effect and may cause sleep disturbances in some people if taken in the evening or just before bedtime. If you find that ginseng is causing you sleep problems, taking it earlier in the day is advisable. It may also be helpful to combine ginseng with a meal to minimise possible stomach discomfort.
