Sourced from Chinese club moss, huperzine A is sometimes touted as a natural treatment for Alzheimer's disease. Available in tea and supplement form, huperzine A has been found to fight the buildup of amyloid beta (a substance that forms the brain plaques associated with Alzheimer's disease) in several laboratory studies.
But while preliminary research suggests that huperzine A shows promise for Alzheimer's treatment, clinical trials on huperzine A are somewhat lacking. What's more, a study published last year in the journal Neurology found that 16 weeks of treatment with huperzine A failed to improve cognitive function in people with mild to moderate Alzheimer's disease.
To reduce your Alzheimer's risk, it's important to follow a diet high in antioxidant-rich in fruits and vegetables, exercise on a regular basis, and keep mentally and socially active as you age. Some studies show that increasing your intake of curcumin (a compound found in the curry spice turmeric) may also protect against Alzheimer's disease.
