Niki, 22-02-2016 Katelijne I buy it in the natural store in Merksem.I think it is a good remedy, have been using it daily for 3 years a few drops of Centella asiatica.The Chinese Li Ching Yuen has lived with it for 256 years, had 32 wives and about 200 children, America has agreed he died 1933. I don't know whether we should believe it, but I will be 74 and still work, reportage in stabbing each other, sometimes have to drive for miles, (last Thursday 357 km) standing in a traffic jam, taking care of the household and I manage that quite well, only my ironing gets stuck sometimes.Response infoteur, 08-09-2016 Let's not advertise gotu kola too much, the retirement age will soon be raised again.Katelijne de Bruycker, 24-08-2015 Is not for sale anywhere, I checked all organic shops and they can't touch them.Response infoteur, 25-08-2015 It is a real medicinal plant and therefore not for sale in organic stores but at some drugstores, both on the Internet and elsewhere.Alec John, 10-11-2014 Is there more information about the effect against Alzheimer's?or Parkinson's?Response infoteur, 12-11-2014 Yes, there is, for example, a Chinese study from 2008 that indicates the effect of gout kola in Alzheimer's: http://www.ncbi.nlm.nih.gov/pubmed/18431001a Also this study of which the full text on the internet mentions this: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3116297/ There is also this study http://www.ncbi.nlm.nih.gov/pubmed /22666298 which has investigated and confirmed the effect in Parkinson's.In general you can say that gout kola has a neuroprotective effect;it protects the cranial nerve cells.Now it is true that it is not a medicine in itself;The intake of this plant should be accompanied by the immediate cessation of products that damage brain cells, such as trans fats in the form of margarine, cooking oil, vegetable hardened oil and frying fat, sugar and white flour products.But for the trans fats are the big culprits.The use of coconut oil and butter is not unhealthy (despite the campaigns that have been conducted against them for years by, for example, the nutrition center.)
