High cholesterol (hyperlipidemia) in Chinese Medicine perspective is considered a “phlegm” condition and is related to the malfunction of liver in regulating the transformation and transportation of cholesterol.

Cholesterol is an essential structural component of all cell membranes. In addition to providing proper membrane permeability and fluidity, cholesterol aids in intracellular transport, signaling and nerve conduction.

These steroid hormones include cortisol, aldosterone, progesterone, estrogen and testosterone. The body makes about 75% of blood cholesterol, while the other 25% comes from food from animal sources.
