Sea of Qi

About CV-6 Sea of Qi

CV-6 Qihai is the body's central reservoir of qi, the vast 'sea' from which all activity, movement, and warmth originate. Located just below the navel on the midline, it sits within the region of the lower dantian and represents the accessible surface of the body's deepest energy store. While CV-4 Guanyuan connects specifically to original qi and the Kidney system, Qihai has a broader, more general tonifying effect on the body's qi as a whole.

The name 'Sea of Qi' indicates an inexhaustible reservoir, and the therapeutic implications match this imagery. Where other qi-tonifying points work on specific organ systems (ST-36 on the Spleen-Stomach, LU-9 on the Lung), Qihai tonifies qi at a level that precedes organ differentiation -- it strengthens the body's fundamental vitality before it is allocated to specific functions. This makes it the point of choice for generalized qi deficiency, where the patient is simply depleted in every way: tired, weak, pale, short of breath on exertion, and lacking motivation.

In martial arts and qigong traditions, the lower dantian area (encompassing both CV-6 and CV-4) is the center of power and stability. Practitioners cultivate awareness at this point to build internal strength, root their stance, and develop the capacity for sustained effort. The breathing technique of 'sinking the breath to the dantian' -- allowing the abdomen to expand with each inhalation while focusing attention below the navel -- directly stimulates Qihai and is considered foundational to all internal cultivation practices.

How to Find This Point

Measure about two finger-widths directly below the navel on the midline. The point is slightly above the midpoint between the navel and CV-4.

Tonifies qi, strengthens the body, warms the yang, regulates qi, resolves dampness, benefits the lower abdomen

General weakness, fatigue, qi deficiency, abdominal distension, hernia, diarrhea, enuresis, menstrual irregularity, post-illness recovery

TCM Actions

Tonifies qi and yang, warms the Lower Jiao, regulates qi, resolves dampness, tonifies the Kidneys

Self-Care Use

Press below the navel (about two finger-widths down) for general fatigue, weakness, and low energy. The 'Sea of Qi' is exactly what it sounds like -- a vast reservoir of vital energy in the lower abdomen. Gentle sustained pressure here while breathing deeply is one of the simplest and most effective energy-building practices. Best done lying down. Placing warm hands on this area while focusing on slow abdominal breathing for 5 minutes is a potent daily vitality practice.
