Radish Seed

Radish Seed

In the world of traditional Chinese medicine (TCM), certain herbs and seeds have been used for centuries to promote healing and overall well-being. One such seed, Lai Fu Zi, also known as Radish Seed, has been a staple in TCM and is revered for its remarkable properties. This article will delve into the wonders of Lai Fu Zi, exploring its uses, treatment principles, and properties.

Lai Fu Zi: A Versatile Seed

Lai Fu Zi, scientifically known as Raphani Semen, is derived from the radish plant (Raphanus). This versatile seed has been used for generations to alleviate various health concerns, particularly those related to digestion and the respiratory system. The Japanese name for Lai Fu Zi is raifukushi, which further highlights its widespread use in Eastern medicine.

Usage and Administration

To harness the benefits of Lai Fu Zi, it is often administered in the form of a liquid herbal glycerite. It is recommended to shake the bottle well before use and consume 20-30 drops three times a day, or as directed by a practitioner. The liquid can be mixed into a glass of water, tea, or juice for easier consumption. Although glycerites can be taken directly, some may have an unpalatable taste, making it preferable to dilute them into a beverage.

Materia Medica Categories

Lai Fu Zi falls under the "Relieve Food Stagnation" chapter and section in the Materia Medica. This classification highlights its effectiveness in addressing food-stagnant and excess-type conditions, which are commonly associated with indigestion and bloating.

Treatment Principles

The use of Lai Fu Zi is based on several treatment principles, which include:

  1. Transforming phlegm: Lai Fu Zi assists in breaking down and expelling phlegm, providing relief from respiratory issues.
  2. Reducing food stagnation: By aiding digestion, the seed helps to alleviate symptoms of indigestion and bloating.
  3. Promoting smooth flow of Qi: Lai Fu Zi plays a role in balancing and promoting the smooth flow of vital energy (Qi) within the body.
  4. Eliminating distension: The seed's properties help to reduce abdominal discomfort and distension.
  5. Reducing phlegm: Lai Fu Zi is effective in reducing phlegm production, leading to clearer airways and improved respiratory function.

Properties and Channels

Lai Fu Zi has a neutral property, which means it is neither hot nor cold, making it suitable for various conditions. It is associated with three channels in TCM: the lung, spleen, and stomach, which are linked to respiratory and digestive functions.

The seed boasts two primary tastes: acrid and sweet. The acrid taste contributes to its ability to break down phlegm and promote the smooth flow of Qi, while the sweet taste has a soothing effect on the digestive system.


While Lai Fu Zi offers numerous benefits, it is essential to exercise caution and avoid long-term use. Always consult with a qualified TCM practitioner before incorporating Lai Fu Zi or any other herbal remedy into your wellness routine.


Lai Fu Zi, the humble radish seed, has been a cornerstone of traditional Chinese medicine for centuries. Its ability to transform phlegm, reduce food stagnation, promote the smooth flow of Qi, and eliminate distension makes it a valuable addition to the TCM pharmacopeia. As with any herbal remedy, it is crucial to seek guidance from a qualified practitioner before incorporating Lai Fu Zi into your daily routine.
