Turtle Shell: Benefits and Uses in Traditional Chinese Medicine (TCM)

The turtle shell, also known as the plastron or carapace, is a key ingredient in Traditional Chinese Medicine (TCM). Derived from the Reeves' turtle (Chinemys reevesii), it is known for its calming properties and ability to restore vitality by nourishing yin and supporting key organs like the heart and kidneys.

Properties and Characteristics

Taste and Nature: Salty, slightly sweet, and mildly cooling in nature.

Target Organs: Heart, liver, and kidneys.

Medicinal Part: The dorsal (carapace) and ventral (plastron) shell of the Reeves' turtle.

The turtle shell is recognizable by its oval, slightly domed shape, with distinct ridges and a dark brown to black coloration. When prepared for use, it is cleaned of residual tissue and dried.

How to Use Turtle Shell in TCM

Dosage: Typically 9–24g, usually boiled as a decoction.

Preparation: The turtle shell is collected year-round, with autumn and winter being the preferred seasons. After harvesting, it is either boiled to remove the turtle or sun-dried. Residual meat is cleaned off to ensure purity.
