[What is Huperzine A]

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. 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’s 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’s 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.

[Function] Used in alternative medicine, huperzine A has been found to act as a cholinesterase inhibitor, a type of medicine used to prevent the breakdown of acetylcholine (a chemical essential to learning and memory).

Not only used as a treatment for Alzheimer’s disease, huperzine A is also said to enhance learning and memory and to protect against age-related cognitive decline.

In addition, huperzine A is sometimes used to boost energy, increase alertness, and aid in the treatment of myasthenia gravis (an autoimmune disorder that affects the muscles).

DESCRIPTION: Cholesterol appears to stimulate the growth of human breast cancer cells, which may explain why phytosterol-rich foods such as pumpkin seeds are associated with reduced breast cancer risk.

If cholesterol increases breast cancer risk, what about the use of cholesterol-lowering drugs? That’s the subject of my next video, Statin Cholesterol Drugs and Invasive Breast Cancer (https://nutritionfacts.org/video/statin-cholesterol-drugs-and-invasive-breast-cancer/).

Other foods I mentioned protective against breast cancer include:
• Broccoli (Broccoli vs. Breast Cancer Stem Cells https://nutritionfacts.org/video/broccoli-versus-breast-cancer-stem-cells/ and Breast Cancer Survival Vegetable https://nutritionfacts.org/video/breast-cancer-survival-vegetable/)
• Soy (Breast Cancer Survival https://nutritionfacts.org/video/breast-cancer-survival-and-soy/ and Soy and BRCA Breast Cancer Genes and Soy https://nutritionfacts.org/video/brca-breast-cancer-genes-and-soy/)
• Flax seeds (Flaxseeds & Breast Cancer Prevention https://nutritionfacts.org/video/flaxseeds-breast-cancer-prevention/)

Some I didn’t mention include:
• Nuts (Tree Nuts or Peanuts for Breast Cancer Prevention? https://nutritionfacts.org/video/tree-nuts-or-peanuts-for-breast-cancer-prevention/)
• Greens (Preventing Breast Cancer by Any Greens Necessary https://nutritionfacts.org/video/preventing-breast-cancer-by-any-greens-necessary/)
• Mushrooms (Breast Cancer vs. Mushrooms https://nutritionfacts.org/video/breast-cancer-vs-mushrooms/)
• Sea vegetables (Which Seaweed Is Most Protective Against Breast Cancer? https://nutritionfacts.org/video/which-seaweed-is-most-protective-against-breast-cancer/)
