In Traditional Chinese Medicine (TCM), Feng Jiao belongs to the 'Herbs for external application' category. Like the name indicates, this category of herbs is used mostly for external application in the form of powders, pastes or ointments. As such they are used to treat trauma, inflammation, swelling, bruises, bleeding, pain and so forth.

Furthermore Feng Jiao is Warm in nature. This means that Feng Jiao tends to help people who have too much 'Cold' in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Cold in their body are said to either have a Yin Excess (because Yin is Cold in nature) or a Yang Deficiency (Yang is Hot in Nature). Depending on your condition Feng Jiao can help restore a harmonious balance between Yin and Yang.

Feng Jiao also tastes Pungent. 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 Feng Jiao tends 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.

The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Feng Jiao is thought to target the Spleen and the Liver. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Liver on the other hand is often referred as the body's "general" because it is in charge of regulating the movements of Qi and the Body Fluids. It also takes a leading role in balancing our emotions.
