Hypertension
The condition is related to an imbalance of the yIn and Yang aspectos of the Kidney Liver, or to an over-abundance of Phlegm and Dampness.
The Liver is dependent on the Kidney Yin to "moisten and soften" it. If  the Kidney Yin becomes deficient, it may cause the Liver Yang to grow excessive, which in turn may further exhaust the Kidney Yin. If the imbalance continues to escalate in this manner, the Liver Yang excess generates fire, which may stir up interior Wind.  Unless held in check, the condition known as "penetrating Wind" or stoke, may ultimately result.
The condition of excessive Liver Yang is associated with such symptoms as headache, dizziness, insomnia and tinnitus and is often accompanied by the appearance of Phlegm. Because of the mutual dependency of Yin and Yang, should the Yin functions be adversely affected as described above, the Yang functions may soon follow, leaving both Yin and Yang in a deficient state.
What in Western medicine is called hypertension usually corresponds to one of the five distinct patterns in TCM.
