【归经】入肾经，是大力辅助元阳的药物。（兼有补剂作用，专门兴起阳事，因强健筋骨故能兴阳）
【前论】李时珍说：锁阳的功效，不外乎润燥养筋，治疗痿弱无力罢了。大致与肉苁蓉相似。

[Indications] Primarily greatly tonifies Yin Qi, benefits Essence and Blood, and promotes bowel movements. For debilitated individuals with dry and constipated stools, Suo Yang can be used in place of Rou Cong Rong (Cistanche) to cook porridge; if there is no dryness or constipation, do not use.
[Meridian Tropism] Enters the Kidney Meridian. It is a potent agent for assisting Yuan Yang. (Acts as a tonic, specifically promoting sexual function, strengthening tendons thereby enabling erection.)
[Preliminary Discussion] Li Shizhen said: The efficacy of Suo Yang does not go beyond moistening dryness, nourishing tendons, and treating flaccidity and weakness. It is roughly similar to Rou Cong Rong (Cistanche).

[Contraindications] Miao Xiyong said: Contraindicated for patients with chickenpox/smallpox who have Qi deficiency, weak Spleen and Stomach, diarrhea, lack of appetite, and clear, copious urination.

Pu Huang (Typhae Pollen):
Taste is sweet and acrid. Nature is neutral. Non-toxic. It absorbs the Yin Qi of the earth and simultaneously acquires the acrid flavor of Metal to generate. Its action can ascend and descend; it belongs to Yin within Yang.
[Indications] When used raw: Primarily moves blood and resolves stasis, unblocks meridians, promotes urination, dispels cold and heat from the heart, abdomen, and bladder, and treats traumatic injuries from falls and blows, as well as various swellings from sores and boils.
[Meridian Tropism] Enters the Liver and Pericardium meridians. It is an agent that cools the blood, invigorates blood circulation, dissipates nodules, and clears heat. (Raw form acts as a lubricating/slipping agent; stir-fried form acts as both a lubricating and astringent agent.)
[Preliminary Discussion] Tao Hongjing said: This is the yellow pollen found on the flowers of the Cattail plant. It is highly effective in treating blood disorders. Lei Xiao said: It is a blood-level medicine for the Hand and Foot Jueyin meridians; therefore, it can treat blood diseases.
[Contraindications] Miao Xiyong said: Contraindicated for all cases of labor injury fever, Yin deficiency with internal heat, and absence of blood stasis.
The above are classified as Slippery/Lubricating Agents, included in the Grass Category.
