When choosing this herb, look for evenly dried pieces, no mold, no musty odor and a clear source. Proper processing and storage are important for safe herbal use.

2. Related names of Piper Kadsura Vine

Piper Kadsura Vine is also known as Hai Feng, Dây hải phong or Hai Feng Teng in herbal practice.

Scientific name: Caulis Piperis Kadsurae. Pinyin name: Hai Feng Teng. Chinese name: 海风藤.

In traditional texts, the name “feng teng” often refers to vine herbs used for wind-damp pain. However, each herb has its own nature, flavor and action, so correct identification is important when buying or combining herbs.

3. Natures, flavors and meridian entry

According to TCM, Piper Kadsura Vine has a Pungent and Bitter flavor with a slightly Warm nature. The Pungent flavor helps disperse wind and open blockage. The Bitter flavor helps dry dampness and reduce heaviness. Its slightly Warm nature makes it more suitable for soreness that becomes worse in cold, damp or rainy weather.

Hai Feng Teng commonly enters the Liver and Kidney meridians. The Liver is related to tendons, while the Kidney is associated with bones, the lower back and knees. For this reason, this herb is often used when tendon tightness, stiff joints, lower back soreness, weak knees or limb numbness appear in a wind-cold-damp pattern.
