Is it the same as Gan-yang-sang-hang (Liver Yang Hyperactivity)?

Both are used in connection with a sensation of heat in the upper body, but they are not exactly the same. Gan-hwa emphasizes the nature of the heat, while Gan-yang-sang-hang emphasizes the pattern of energy shifting upward.

Is it related to liver function levels?

They do not correspond directly. Liver function tests check for actual liver cell damage and biliary issues, whereas Gan-hwa describes a cluster of symptoms from a Korean medicine perspective.

What is evaluated during the medical consultation?

We examine the location of the heat sensation, its relationship with stress, headaches, bloodshot eyes, dry mouth, digestion, sleep, and changes in menstruation.

Is any heat that rises when feeling nervous considered Gan-hwa?

No. Autonomic nervous system reactions, menopause, thyroid issues, and medications can cause similar changes. After checking the onset of symptoms and test results, we determine if there are actual clues indicating Gan-hwa.

Gan-hwa (Liver Fire) does not mean there is actual heat in the liver

Gan-hwa is a Korean medicine term used to describe a pattern of symptoms that appear together, such as facial flushing, headaches, irritability, bloodshot eyes, a bitter taste in the mouth, and sleep disturbances. It does not mean the anatomical liver has a high temperature or inflammation, nor is it a name determined solely by emotional state.

Commonly confused terms and their differences: Hepatitis, fatty liver, and biliary diseases are medical conditions confirmed through blood tests and imaging. Even if the names sound similar to Gan-hwa, they cannot be used interchangeably. Headaches, flushing, and insomnia also require checking for other causes such as thyroid issues, medication, blood pressure, or menopause.
Information to record before your visit: Please note the time when headaches and facial heat sensations begin, as well as your blood pressure, sleep, alcohol and caffeine intake, medications, and menstrual changes. You must separately inform your medical provider if you experience yellowing of the eyes or skin, dark urine, or pain in the upper right abdomen, regardless of Korean medicine expressions.
Scope of this material: WHO data was used to verify the traditional medicine term Gan-hwa, and MedlinePlus data was used to distinguish the medical evaluations required for liver disease. This explanation of terms does not diagnose liver disease or prove the efficacy of Korean medicine treatments. Jaundice, changes in consciousness, or severe abdominal pain require prompt medical evaluation.

Heat and Cold ColumnTreatment varies depending on the cause of chest heat sensation, such as heartburn, throbbing, or tension

Heat and Cold ColumnBurning Mouth Syndrome: Can the inside of my mouth feel burning even if tests are normal?

When the tongue and mouth feel as if they are burning but look normal on the outside, we explain how to distinguish Burning Mouth Syndrome from other causes and what is evaluated in Korean medicine treatment.

We categorize the causes of facial flushing into thyroid issues, menopause, medication, skin reactions, and heat-cold imbalance, and explain how the direction of herbal medicine and acupuncture treatment varies by cause.

Medical GuideWhat else should I examine when my face feels hot or heat rises to my face?

Facial heat sensations can be divided into facial flushing where redness is visible, upper body heat where only heat is felt, and patterns where sweating and palpitations occur together. Even if there are no abnormalities in tests, sharing the time of occurrence and accompanying symptoms can help find a more specific direction for Korean medicine treatment.

Medical GuideIf my face is hot and my feet are cold, is it Sangyeol-Hahan (upper heat, lower cold)?

Even if test results are normal, heat in the face and coldness in the feet and lower abdomen are real symptoms that can disrupt sleep, meals, and outings. In Korean medicine, this is viewed as a distribution of heat and cold known as Sangyeol-Hahan, and the treatment direction is determined based on the timing and sequence of upper and lower symptoms and their connection to sweating, throbbing, digestion, and sleep.
