02PROGRAM GOALS
How was Bigam Capsule made?
Dr. Bongha Ryu, Honorary Director, developed Gambisan together with the Department of Acupuncture and Moxibustion at Kyung Hee University while serving as director of the Kyung Hee University Herbal Medicine Research Institute. Gambisan was studied as an herbal medicine prescription to help fat metabolism, including for overweight patients who had difficulty exercising due to joint pain. Bigam Capsule is made by extracting this prescription into a highly concentrated extract and placing it in capsules.

04STEPS
From Weight Loss to Maintenance, a Step-by-Step Plan
We create an individualized plan based on your constitution, symptoms, and pace of weight loss. The duration of use and concentration of the medicine are determined in consultation with the medical team.
- STEP 1
Intensive Weight-Loss Phase (3 Months) — Bigam Capsule U
We view obesity as a chronic inflammatory state in which waste products (damjeok) and toxins accumulate due to weakened gastrointestinal function. This phase helps reduce edema by supporting waste product elimination and detoxification, while beginning active weight loss. A detox decoction to support liver function and intestinal detoxification or Cheongjang Capsule for retained stool management may also be used.
- STEP 2
Homeostasis-Overcoming Maintenance Phase (3 Months) — Bigam Capsule U~M
This phase helps restore weakened metabolism and circulation and supports hormone balance so that appetite control can be regained. Insulin resistance management is also considered. This is an important period for creating a new set point, the weight the body tries to maintain, at the reduced weight.
- STEP 3
Yoyo Prevention Maintenance Phase (3~6 Months) — Bigam Capsule Y
With any diet, yoyo weight regain can occur if maintenance is neglected. We recommend a maintenance prescription for about 3~6 months to help preserve the restored metabolic capacity and new set point. The duration varies by individual.
05PROGRAM
Which Bigam Capsule is right for me?
We prescribe one of three types according to your symptoms and constitution.

Bigam Capsule M (Mild)
Recommended for those who are worried because they have never taken diet herbal medicine or conventional medication, or those who had significant discomfort with previous diet medications.

Bigam Capsule U (Ultra)
This prescription is designed for the active weight-loss phase. It is recommended for those who have experience taking diet medication and want active weight loss.

Bigam Capsule Y (Yoyo)
This is a mild prescription for maintenance after the weight-loss phase. It was made with long-term use in mind and is needed for those who want to maintain their reduced weight.
06PROGRAM
If constitution improvement is needed first — Bigam Detox Herbal Decoction

Bigam Detox Herbal Decoction (Personalized Decoction)
This is a personalized decoction based on improving liver function and intestinal detoxification, while also examining the conditions that may underlie obesity. It is recommended for those for whom other diet medications were not effective or caused severe side effects, and for those who had difficulty dieting because of chronic illness.
