Contradictory results are likely due to the varying quality of ginseng used by various study groups, as well as poor or inconsistent research procedures. Many researchers are calling for more rigorous investigations on these promising herbs to verify their effectiveness and safety. Choosing a Brand With ginseng, you get what you pay for. Ginseng can be expensive because there are limited supplies of high-quality Korean ginseng and because the herb takes a long time to cultivate. While cheaper products are available, they tend to be of poorer or uncertain quality and authenticity.
Some researchers even report instances where ginseng has been substituted with a different herb.
When Problems Arise While adverse events are rare when ginseng is taken in moderate doses using standardized preparations, mild side effects can occur like insomnia, irritability, melancholy, morning diarrhea, skin rashes or anxiety. These usually stop if you decrease the amount taken or discontinue taking the herb for at least two weeks. People who decide to use ginseng for longer periods often alternate two to three weeks of usage with a two-week rest. People who take ginseng concurrently with medication need to practice extra caution. However, as with any medicinal herb, be sure to consult with your health care practitioner before taking ginseng for any period of time.
