In Traditional Chinese Medicine (TCM), radish seeds are plants that belong to the 'Herbs that relieve Food Stagnation' category. These herbs typically possess digestive and Food moving properties as they relate to the Stomach and Spleen. Some of these herbs are high in digestive enzymes and have varying specific abilities to help with the digestion of food.
Furthermore radish seeds are plants that are Neutral in nature. This means that radish seeds typically don't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang Excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin Excess. The Neutral nature of radish seeds means that you don't have to worry about that!
Radish seeds also taste Pungent and Sweet. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like radish seeds tend to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food. On the other hand Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such radish seeds are thought to target the Spleen, the Stomach and the Lung. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Stomach on the other hand is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. In addition to performing respiration, the Lungs are thought in TCM to be a key part of the production chain for Qi and the Body Fluids that nourish the body.
