1. Origin and description

Acanthopanax Bark belongs to the Araliaceae family and is obtained from the stem bark or root bark of Acanthopanax trifoliatus after harvesting, cleaning, and drying. The herb has been used in traditional practice in Vietnam and several other Asian countries.

The plant is a small shrub or climber that often grows in mountainous forests, forest edges, and moist areas. Its stems bear many small thorns, a useful feature for distinguishing it from other herbs called Ngũ gia bì.

The leaves usually have three oval to lance-shaped leaflets with slightly serrated margins. The flowers are small and arranged in umbels, while ripe fruits become dark to nearly black.

The dried bark is yellow-brown to gray-brown, mildly aromatic, and slightly Pungent and Bitter. Good-quality material should be dry, thick, low in impurities, mold-free, and clearly sourced.

In TCM, the herb is mainly used to dispel Wind-Dampness and support the musculoskeletal system. Traditional applications include:

• Dispelling Wind-Dampness: Commonly referenced for aching joints, stiffness, and discomfort associated with Wind-Dampness patterns.
• Strengthening tendons and bones: May be included in formulas for weak or tired lower back, knees, and limbs.
• Supporting numbness of the limbs: Traditionally used when the hands or feet feel numb, heavy, or uncomfortable.
• Supporting lower back and knee comfort: Often combined with other herbs when soreness or weakness affects mobility.

5. Acanthopanax Bark vs. Schefflera Bark

Acanthopanax has many small thorns on its stems and usually has leaves composed of three leaflets. Schefflera typically has palmately compound leaves with several leaflets spreading outward like a bird’s foot.

Traditional properties
Acanthopanax Bark is Pungent, Bitter, and Cool and is commonly used to dispel Wind-Dampness and support joints. Schefflera Bark is warmer and traditionally emphasizes tendons, bones, and physical weakness.
