What potential effect can high doses of ginseng have?

High doses of ginseng can lead to liver problems, particularly due to the presence of certain compounds in the herb that may cause hepatotoxicity. Some research suggests that excessive intake of ginseng can stress the liver and potentially lead to conditions such as hepatitis or elevated liver enzymes. This concern is more pronounced with long-term use or high doses, making it critical for individuals to use ginseng responsibly and be aware of possible adverse effects on liver health.

In contrast, while enhanced cognitive function is often claimed as a benefit of ginseng, this effect is generally associated with lower doses rather than high doses. Increased cholesterol and heart arrhythmias are also not widely recognized as common outcomes of high ginseng consumption, making them less relevant when discussing the herb's adverse effects.
