Commentary:

Fenglong is the point of choice for transforming phlegm anywhere in the body, no matter how it is formed.

Phlegm is formed in the body, either by;
i) heat condensing bodily fluids,
ii) stagnant liver Qi impairing the circulation of fluids,
iii) deficiency of any of the organs responsible for water flow in the body; Lungs (Upper Jiao) ,Spleen (middle Jiao) , or Kidneys (Lower Jiao).

Of these, the Spleen is probably the most important. It is said that phlegm originates in the Spleen and is stored in the Lungs. It is the Spleen's job to transform food and water into Qi and transport it to the rest of the body. When the Spleen's function is impaired or deficient, Qi does not move and hence fluids do not move. They accumulate and eventually phlegm is formed.

Of all disharmonies in TCM, phlegm is generally considered the most difficult to treat and is manifest in a wide variety of forms in all parts of the body. In modern terms, phlegm appears in different forms, as nodules, cysts, lumps etc., that can become cancerous.

Fenglong is the Luo-Connecting point of the Stomach channel that connects it to the Spleen channel and the Spleen, which helps to explain its effectiveness in treating phlegm and other Spleen related disharmonies.

Fenglong is an essential point for cough with phlegm either due to cold (phlegm is white or clear) or due to heat (phlegm is yellow, brown or green). When phlegm obstructs the passageways, the Lung is unable to descend Qi properly and it rebels upward manifest by coughing.

As the primary channel of the Stomach runs through the chest Fenglong is considered an important point for chest pain due to phlegm accumulation but it is also well used for muscle strain or sprain.

When severe emotional depression gives rise to a pattern known as phlegm or phlegm-fire 'misting the heart', Fenglong is indicated. According to chinese theory, the Heart Houses the Spirit. Disharmonies of the Heart are indicated by psycho-emotional disorders. When fire predominates there are symptoms such as mad laughter and wild behaviour. When phlegm predominates the symptoms are lethargy, mental confusion or stupor. Either way, Fenglong is the point of choice for resolving phlegm or phlegm-fire in the Heart.
