Ash Tree Extract Could Lower Blood Sugar in Obese Adults

| February 28, 2017

I probably don’t need to remind you of the unpleasant and often dangerous side effects of prescription diabetes drugs. I have written about them often enough in previous posts, for instance here, here and here. So, I am always keen to bring you news of non-drug approaches for controlling blood sugar levels and dealing with its complications. Even if you are not diabetic, levated blood sugar levels can increase your risk of cardiovascular disease that could lead to a heart attack or stroke – and, if you are older, it could hasten the onset of dementia.

Specific herbs have been found to offer similar benefits to pharmaceuticals, but are usually safer and freer from side effects – although, of course, you should always comply with dosage instructions and other safety information. While many antidiabetic herbs have come to light in the traditional medicine of people in far-flung places like India and China, help is also at hand much nearer to home, from the European ash tree.

The scientific name of this magnificent tree is Fraxinus excelsior. And recent research has shown that an extract made from its seeds has some remarkable properties. A research team at the University of Navarra in Pamplona, Spain looked at its effects in non-diabetic adults aged 50 to 80 who were overweight or obese. This was a double-blind, placebo-controlled, crossover trial, in which each participant took either the ash seed extract or placebo for three weeks and then, after a one-week “washout” period, switched to the other intervention.

Compared to the baseline level at the start of the study, blood sugar dropped by 28 per cent after three weeks of treatment with the ash seed extract. This is an impressive reduction, considering that the people in the study were not diagnosed as being diabetic and they only took the extract for a period of three weeks. The patented ash seed extract used in this study is called Glucevia and it can be found in several supplements available in the UK and the USA. A safe dose is up to 1000 mg a day.

If you are taking medication, talk to your doctor before starting with Glucevia. In my next blog post, I’ll tell you about some other herbs that have been shown to reduce blood sugar safely.

Wishing you the best of health,
