Full of minerals, nutrients, amino acids and enzymes, our products provide a multitude of health benefits. All of our products are free of pesticides, pollutants & chemicals!

Our Dietary Supplements

All of our foods are potent natural adaptogens that restore the body's balance and homeostasis, thus helping the body readjust better to stress or disease conditions.

Eastern Medicine

Over 90% of all diseases are chronic, or stem from chronic conditions. Towards these diseases, modern Medicine has found effective means to alleviate the signs or symptoms but less often are the roots addressed. Eastern Medicine on the other hand attempts to heal the whole patient rather than just the disease symptoms


Our group seeks to promote and restore health through the use of a comprehensive range of products that represent the cutting edge of 21st century biomedical technology. We believe that the most effective way to achieve this is to combine the best practices from both Western and Eastern Medicines.

Our Green Tea Extract is from natural green tea leaves by implementing a highly proprietary biotechnology process to a final purity of 99.6%. Each capsule of Green Tea Essence contains high proportions of catechin (as EGCg, exceeding 86%). As confirmed through numerous scientific experiments, this essential component helps the human body adjust various physiological functions, enhance metabolism, alleviate fatigue, maintain a healthy ecological distribution of useful bacteria (for example, Bifidobacterium longum), and enhance gastro intestinal functions. It also enhances dental health and alleviates halitosis.

90 capsules per bottle / 400mg per serving

Suggested Usage: 1-2 capsules 3 times a day.

Contains no preservatives, artificial coloring, flavoring or yeast.

What to look for when purchasing Green Tea Essence

When choosing a Green Tea supplement, the most important factor is the EGCg content. Epigallocatechin gallate (EGCg) is a type of catechin that has very strong anti-oxidant properties. Oxidation, which is the damage caused by free radicals, is associated with a number of chronic diseases including cancer, arteriosclerosis, heart diseases and accelerated aging. Studies have shown that EGCg may protect our cells from oxidative damage from free radicals.
