Huperzine A, is a naturally occurring sesquiterpene alkaloid found in the extracts of the firmoss Huperzia serrata. The botanical has been used in China for centuries for the treatment of swelling, fever and blood disorders. Recently in clinical trials in China, it has demonstrated neuroprotective effects. It is currently being investigated as a possible treatment for diseases characterized by neurodegeneration – particularly Alzheimer’s disease. [Wikipedia]

Dược Lực Học : Huperzine A is an alkaloid derived from Huperzia serrata (which is available as an herbal product in the US). It is under investigation as an acetylcholinesterase inhibitor. Clinical trials in China have shown that huperzine A is comparably effective to the drugs currently on the market, and may even be somewhat safer in terms of side effects.
Cơ Chế Tác Dụng : Huperzine A, is a naturally occurring sesquiterpene alkaloid found in the extracts of the firmoss Huperzia serrata. The botanical has been used in China for centuries for the treatment of swelling, fever and blood disorders. Recently in clinical trials in China, it has demonstrated neuroprotective effects. It is currently being investigated as a possible treatment for diseases characterized by neurodegeneration – particularly Alzheimer’s disease. [Wikipedia] Huperzine A has been found to be an inhibitor of the enzyme acetylcholinesterase. This is the same mechanism of action of pharmaceutical drugs such as galantamine and donepezil used to treat Alzheimer's disease.
Chỉ Định : For the treatment of Alzheimer's disease.
