Ginseng may depress or stimulate the central nervous system. This means you may feel drowsy or you may feel nervous, excited, or agitated. This becomes less of a problem if you use ginseng continually or if you take a smaller dose. Diabetics should use ginseng with caution because of its effect in lowering blood sugar. Check with your doctor before taking ginseng because your dosage of insulin or diabetes medicine may need to be adjusted.
Some natural remedies have the same effects as prescription medicines.
This means there is a danger of being overmedicated. If you have any unusual effects while taking any natural remedy, get advice from a doctor right away. Natural remedies and prescription medicines may interact. Lack of standardization may result in products with different strengths and effects. Lack of quality control may allow contamination of products.
