Boyak is the Korean name for Herbal Decoction. Literally, it means Tonic Supplement. There are two advantages of Korean herbal medicine, ‘Boyak'. The first is that it solves the root cause of the problem and even unseen symptoms. Korean herbal medicine aims at changing the body system into an ideal state in itself with the principle of solving the root cause rather than just treating the symptoms. The second advantage is that it has almost no side effects. The principle of Korean herbal medicine is that although it takes a longer time the condition will be slowly improved non-surgically into an idealistic state by solving the root of the problem. The secrets of Jaseng's exclusive Boyak's have been passed down through seven generations so far. Through the experience and expertise of Dr. Joon Shik Shin and his ancestors some of the most effective Herbal Decoctions have been developed. The herbal decoctions effect have been tested and proven in Jaseng's Research Center of Biotechnology.




The Scientificallly proven Effect of Jaseng's Medicine
Yookgongdan, widely known for its effect in patients suffering from Chronic Fatigue, and students has been proven to improve brain function through the analytic research study carried out by the neuroscience research team at University of California, Irvine, and Jaseng Research Center of Biotechnology. The results of this experiment were published in the October 2004 issue of the International Journal of Neuroscience. Furthermore, through the joint research conducted by Natural Products Research Institute of Seoul National University, and Jaseng Hospital of Oriental Medicine a new substance ‘Shinbarometin’ was discovered from Jaseng’s Chuna Medicine. Shinbarometin has been proven through molecular biological experiments and animal experimentation to be effective in anti-inflammation, bone regeneration, nerve restoration, and muscle relaxation. Jaseng has obtained a U.S. substance patent and a Korea Patent for Shinbarometin. In addition, Jaseng has joined hands with Korea’s leading pharmaceutical company Green Cross Pharmaceuticals in the development of a new medicine for bone and joint disorders.

Selecting Highest Quality Herbs
Jaseng Hospital uses top quality herbs solely approved by Korea Pharmaceutical Company, and produced in Korea. For instance, herbs often used in decoctions such as Maximowiczia typical are grown in Jaseng's own organic herb farm.

Maintaining Safety Through Strict Inspection Process
No matter how good the herb may be for your health, once agricultural chemicals or heavy metals contaminate it, the original effect would be hard to depend on. At Jaseng Hospital of Oriental Medicine, all medicine and herbs go through a strict inspection process in Jaseng's own Research Institute of Biosciences in order to provide the highest quality.

Decocted With Devotion and Cleanliness
Jaseng Oriental Medicine is prepared with devotion and cleanliness. Jaseng’s Decoction Lab maintains the highest level of cleanliness by executing daily sanitation inspections, and it goes through weekly quarantine inspections.
