A recent clinical trial, funded primarily by the NIH and published in the Journal of the American Medical Assn.
, reported that ginkgo biloba doesn't prevent cognitive impairment, compared with dummy pills.
The big fault of the clinical trial is that they selected wrong people.
Subjects included were between the ages of 75 and 96, who were too old to reverse the dead brain cells.
The key of Alzheimer's disease is to prevent, and there is no cure for it.
It is true that ginkgo biloba can't prevent dementia for very old people; neither does any conventional chemical drugs.
It demands impossible on herbs.
It is basic medical science that once a brain cell dies it's gone forever, since brain cells can't regenerate.
Fortunately, at early stage of Alzheimer's, only a waxy plaque is formed and brain cells are not dead yet.
It is possible to clean the plaque and save these brain cells.
The sooner you clean the plaque, the easier you can slow down the dementia.
The best time to prevent Alzheimer's disease is at age 65, when you start to have occasionally lapses in both short- and long-term memory.
A Chinese herbal formula, called healthy artery granule, can prevent Alzheimer's disease at early ages.
It has an 85.
89% effective rate according to a clinical trial ( Zhuang Haixin and Yu Zhaoan, Jilin Journal of Traditional Chinese Medicine, 4(28), 2008 ).
78 patients between the ages of 65 and 78 were treated with this herbal product for 2 months, 6 grams a time, three times a day.
39 patients between the ages of 66 and 75 were treated with a chemical drug Piracetam tablets for 2 months, 0.
8 gram a time, three times a day.
Results: According to brain electrical activity mapping, 85.
89 % of herb takers were improved; 41.
03% of Piracetam takers were improved.
Conclusion: This herbal formula is better than chemical drug Piracetam for Alzheimer's disease treatment.
