Lindera Root

Traditional Use

Primary Actions

• Promotes Qi movement and alleviates pain - Wu Yao is a classic warming Qi regulator for abdominal pain, distention, cold stagnation, and constrained movement in the chest, epigastrium, or lower abdomen.
• Warms the Kidneys and disperses cold - its traditional lower-jiao use includes cold hernia-type pain, lower-abdominal constriction, and weakness from Kidney cold.
• Reduces frequent urination - when Kidney and Bladder cold cause frequent, clear urination, Wu Yao helps restore containment and warmth.

Secondary Actions

• Wu Yao is unusual because it moves Qi strongly without being especially drying or upward-scattering, which makes it versatile across upper, middle, and lower-jiao cold stagnation patterns.
• Its lower-abdominal and urinary uses are why it appears in both pain formulas and formulas for cold-deficiency urination.

Classic Formulas

• Tian Tai Wu Yao San - one of the defining formulas for cold hernia and lower-abdominal cold stagnation.
• Shao Fu Zhu Yu Tang - lower-abdominal blood-cold pain formula logic in which Wu Yao helps move cold-constrained Qi and ease pain.
• Suo Quan Wan - classic formula for frequent urination and loss of control from Kidney and Bladder deficiency-cold.

Classical References

• American Dragon and TCM Wiki describe Wu Yao as acrid and warm, entering the Lung, Spleen, Kidney, and Bladder, with actions of promoting Qi, dispersing cold, alleviating pain, and reducing frequent urination.
• Traditional formula usage makes clear that Wu Yao's center of gravity is the lower abdomen and urinary system even though it can also regulate middle-burner cold stagnation.
• The herb's history in Tian Tai Wu Yao San and Suo Quan Wan anchors both its pain-relieving and urine-controlling functions.
