Kava Kava also has an antagonistic effect on dopamine. If you are taking a levodopa-based medication for Parkinson's disease, avoid this herb. Of course, you may argue that prescription drugs also cause serious side effects. The difference is that prescription drugs have been laboratory tested and the side effects are known. When dealing with a reputable drugstore, patients are warned of the possible effects.
Many herbal products have no warnings posted at all.
Another danger, like with kava kava, is herbal interactions with prescription drugs. Some herbal remedies counteract the benefits you are supposed too receive from your prescription medications. Other herbal remedies increase the effects of the drugs, and this can be very dangerous, especially in the case of medication for sleeping. Always check with both your doctor and either an accredited herbalist or holistic practitioner before mixing prescription drugs and herbal remedies. Excellent results for thousands of snorers.
