[Abstract summarizes well].
Probably getting ahead of myself, but here's a link from google for "cholinergic herbs".
In the "Chinese Club Moss and Huperizine" section on herbs "that Enhance Acetylcholine" there is a product called Huperzine A which has been scientifically tested for Alzheimer's and here are a series of articles on the product. (The first article is where I found the product and it contains information about other Chinese medicinal herbs.)
Alzheimer's Disease: Treatment with Chinese Herbs
"Currently, there are two treatment approaches to Alzheimer's disease in China: use of complex herbal formulas based on the traditional methods of Chinese medicine, or administration of an alkaloid drug, called huperzine A, derived from the herb huperzia. This drug inhibits the breakdown of the neurotransmitter acetylcholine, allowing more of it available for brain functions, including memory. Huperzine A has passed Phase I trials in the U.S. and it may become available as a prescription drug at the end of this decade."
