Parts used and habitat: Huperzia is a type of moss that grows in China. It is related to club mosses (the Lycopodiaceae family) and is known to some botanists as Lycopodium serratum. The whole prepared moss was used traditionally. Modern herbal preparations use only the isolated alkaloid known as huperzine A.
What Is It? For centuries in the Far East, traditional healers have used a rare moss (Huperzia serrata) found in the colder regions of China to remedy fever and inflammation. Only recently did scientists uncover a remarkable quality in a substance they isolated in the moss. Called huperzine A, the compound appears to have the power to sharpen the mind and potentially ward off the devastating effects of the memory-robbing disease known as Alzheimer's, particularly in its earliest stages. Huperzine A has also been proposed for countering normal bouts of forgetfulness in the general population. Mental improvements associated with huperzine A appear to stem from the compound's ability to inhibit the breakdown of acetylcholine, a brain chemical essential to memory. The only Alzheimer's drugs currently approved by the U. S. Food and Drug Administration work in much the same way. In fact, laboratory findings indicate that huperzine A may be more precise than conventional medications in the manner in which it protects acetylcholine, raising hopes that it could counter memory loss with relatively few side effects. General Interaction Huperzine A is believed to have a synergistic effect when combined with cholinesterase inhibitors, drugs that act in a similar fashion to combat Alzheimer's-related memory loss. So while the combination of these two agents could potentially boost the benefits of both, it could also lead to as yet unidentified negative reactions. Consult a doctor for guidance Cautions ? Although apparently safe over the short term, there is no information on whether huperzine A will lead to long-term complications, especially when used in conjunction with other medications. Consult a doctor to determine your optimal dose of huperizine A. ? Make sure to buy only 99% purified compounds of huperzine A; crude extracts of the moss are potentially toxic and could have sedative effects, which certainly won't sharpen memory. ? Given its mode of action, huperzine A may affect heart rate. For this reason, don't take huperzine A if you have hypertension (high blood pressure) or are pregnant. People with asthma or other respiratory diseases should also use huperzine A with care. ? Side effects of huperzine A may include nausea, vomiting, diarrhea, headache, and muscle cramps. ? Consult a doctor if you are experiencing unusual confusion or memory loss; it's important to have such symptoms professionally examined and treated if necessary.
Indications and usage:
Primary uses: Age-related cognitive decline; Alzheimer disease.
Actions and pharmacology: Huperzine A is an alkaloid found in huperzia that has been reported to prevent the breakdown of acetylcholine, an important substance needed by the nervous system to transmit information from cell to cell. Animal research has suggested that huperzine A ability to preserve acetylcholine may be greater than that of some prescription drugs. Loss of acetylcholine function is a primary feature of several disorders of brain function, including Alzheimer disease. Huperzine A may also have a protective effect on brain tissue, further increasing its theoretical potential for helping reduce symptoms of some brain disorders. In a double-blind trial, people with Alzheimer disease had significant improvement in memory and cognitive and behavioral functions after taking 200 mcg of huperzine A twice per day for eight weeks. Another double-blind trial using injected huperzine A confirmed a positive effect in people with dementia, including, but not limited to, Alzheimer disease. Another double-blind trial found that huperzine A (100?50 mcg two to three times per day for four to six weeks) was more effective for improving minor memory loss associated with age-related cognitive decline than the drug piracetam. Huperzine A has also been shown to enhance memory in adolescent middle school students. A small controlled trial found that 100 mcg of huperizine A two times per day for four weeks was effective in improving memory and learning performance. Although no side effects were reported in this short trial, long-term safety studies are needed before huperizine A is recommended for adolescents or younger children to improve memory and learning performance.
