Animal study: ginkgo strengthens bones
Ginkgo biloba extracts do more than just improve your cardiovascular system and delay ageing processes. According to an animal study done at the Brazilian Federal University of Juiz de Fora, published in Phytotherapy Research, gingko also makes bones stronger. A dose of ginkgo had a better effect than regular osteoporosis medicine in the Brazilian study.
The results below show that the regular medicine worked. The MPBS and DPBS were higher in the positive control group. The cortical thickness of the jawbone also increased.
The Brazilians gave other groups of rats ginkgo in addition to the osteoporosis inducing dexamethasone. The higher the dose of ginkgo, the more firmly their teeth were still planted in their jaw, front and back. See below. The effect was statistically significant at doses of 28 and 56 mg extract/kg/day. Human equivalent of the testes dose: appr. 350-700 mg/day.
The researchers suspect that substances in ginkgo attach themselves to the beta receptor for estradiol in bone cells. Compounds that attach to the receptor have only positive effects. They make bones stronger, stimulate brain cells and inhibit the effects of estradiol that are related to the alpha receptor.
"Extracts of Ginkgo biloba may be effective in the treatment of osteoporosis", the Brazilians conclude.
