Consider a consultation if you have symptoms like these
- You still feel tired after a night of sleep
- You catch colds often and recover slowly
- Exams or work are draining your energy
- You want to regain your strength after a serious illness or surgery
- You want to look after your parents' health

Tonics also need to suit your constitution
Even the same fatigue can have different causes, such as a lack of energy (qi), blood deficiency (a Korean medicine concept), or weakened digestion. A tonic that does not suit your body may not help as much as you expect.
At Woorimbon Korean Medicine Clinic, we examine your constitution and current condition through pulse diagnosis and an interview, then prescribe Gongjindan, Gyeongokgo, or a deer antler velvet tonic. Dr. Yoon personally prepares the Gongjindan.
