Atopic dermatitis, asthma and rhinitis are often regarded as diseases of modern times with no ultimate cure.

A Korean Oriental medicine doctor, however, believes that those incurable illnesses can be cured by increasing lung function through a constant intake of herbal medicine named Pyunkangtang.

The herbal medicine, developed by Seo Hyo-seok, head of Pyunkang Oriental Clinic, was based on the oriental medicine principle that strength originates from the lungs. 

“Pyunkangtang increases the activation of the lungs to help the body inhale more air. The enhanced lung function is believed to improve one’s immune system, appetite and self-curing functions,” Seo said.

“Patients who took my prescription and treatment methods said they were not only cured from the diseases but also became psychologically more comfortable,” he said. “Pyun” and “kang” mean comfort and health, respectively.

The herbal medicine is safe and effective for children who have weaker immune systems and are prone to colds.

“Preventing colds in children is important because when children catch colds, they consume energy that should have been used for their body growth,” Seo said.

The medicine is also effective for skin care.

The doctor said that the lungs are one organ through which the body discharges waste.

“So, making the lungs and colon stronger will help the body discharge waste and activate one’s dermal respiration and supply of clean blood,” he said.

Based on Geumsaengsu, meaning “water formed from metal,” the doctor added 10 different medicinal herbs that are thought to improve the function of the lungs and related organs.

Manufactured by the clinic, the herbal medicine is exported to 31 countries and has cured tens of thousands of patients around the world, the doctor claimed. So far, Seo’s clinic has sold about 1 billion won worth of Pyunkangtang worldwide. The herbal medicine has been selected as one of top Korean oriental medicines by the World-Overseas Korean Trade Association, he added.
