III. Pathogenesis, Efficacy and Treatment

1. Analysis of Pathogenesis

Guizhi Shaoyao Zhimu Decoction The pathogenesis it targets is mainly the obstruction of the channels and collaterals by wind-cold-damp pathogens, resulting in poor qi and blood circulation, and may be accompanied by deficiency of the liver and kidney. Wind-cold-damp pathogens invade the body surface channels and collaterals of the human body, leading to qi and blood obstruction, and pain due to obstruction. As a result, symptoms such as pain in the limb joints and difficulty in flexion and extension occur. If the condition persists, the wind-cold-damp pathogens linger for a long time, easily damaging the liver and kidney, leading to deficiency of the liver and kidney, and loss of nourishment of the tendons and bones, further aggravating the condition. Guizhi Shaoyao Zhimu Decoction is applicable to the syndrome of cold-damp arthralgia with edema and deep and taut pulse. In the formula, aconite root is used to warm yang, dispel cold, and remove dampness and relieve pain. For example, if a patient has been in a cold-damp environment for a long time and the wind-cold-damp pathogens invade the body due to deficiency, initially presenting with symptoms such as joint pain and aversion to cold on the surface. If not treated in time and the condition progresses, symptoms of deficiency of the liver and kidney such as soreness and weakness in the waist and knees, dizziness and tinnitus may occur.

2. Efficacy

- Expel wind and remove dampness: In the formula, drugs such as cinnamon twig, ephedra, and ledebouriella root can expel wind, dispel cold, and remove dampness, so that the wind-cold-damp pathogens in the body surface channels and collaterals can be dispersed, relieving symptoms such as joint pain and swelling.

- Warm the channels and dredge collaterals: Cinnamon twig warms and dredges the channels, promotes qi and blood circulation, makes the channels unobstructed, and improves limb discomfort caused by qi and blood obstruction.

- Nourish yin and clear heat: Anemarrhena asphodeloides nourishes yin, moistens dryness, clears heat and reduces fire, can prevent yin damage caused by warm and dry drugs, and at the same time has a regulating effect on the image of internal heat due to yin deficiency that may occur in the long-term arthralgia syndrome.

- Regulate qi and blood: Paeonia lactiflora nourishes blood, softens tendons and relieves pain, cooperates with drugs such as cinnamon twig, regulates qi and blood, makes qi and blood unobstructed, and relieves pain.

3. Treatment

- Mainly treats arthralgia of all limb joints, emaciation of the body, swelling of the feet as if falling off, dizziness, shortness of breath, and nausea and retching arthralgia syndrome. Arthralgia syndrome is a disease mainly manifested by joint pain, swelling, deformation, and even emaciation of the body and limited joint movement. Guizhi Shaoyao Zhimu Decoction has a good therapeutic effect on arthralgia syndrome caused by wind-cold-damp pathogens obstructing the channels and collaterals, poor qi and blood circulation, and concurrent deficiency of the liver and kidney. When the patient shows severe pain in multiple joints, difficulty in flexion and extension, joint swelling, gradual emaciation of the body, accompanied by symptoms such as dizziness, shortness of breath, and nausea and retching, using this formula can effectively relieve symptoms and improve the condition.

IV. Analysis of the Formula's Meaning of Guizhi Shaoyao Zhimu Decoction

1. Eliminate Wind-Cold-Dampness

When cinnamon twig, ephedra, and ledebouriella root are combined, they can enhance the power of expelling wind, dispelling cold, and removing dampness. Cinnamon twig warms and dredges the channels, ephedra opens the pores, and ledebouriella root expels wind and overcomes dampness. They act together on the body surface channels and collaterals to relieve the wind-cold-damp pathogens from the surface. Atractylodes macrocephala strengthens the spleen and removes dampness, assisting in removing dampness in the body, making the dampness have nowhere to attach. For example, when the human body is invaded by wind-cold-damp pathogens and presents symptoms such as aversion to cold, absence of sweating, joint pain, and heaviness of the limbs on the body surface, these three drugs can quickly play a role, dispelling exogenous pathogens and relieving the exterior syndrome.

2. Harmonize Qi and Blood

Ramulus Cinnamomi warms and dredges the blood vessels, and Paeoniae Radix Alba nourishes the blood and harmonizes the nutrient qi. The two cooperate with each other, one warming and one nourishing, to regulate qi and blood. When qi and blood flow smoothly, the meridians can be nourished, and symptoms such as joint pain can be alleviated. Glycyrrhizae Radix Praeparata cum Melle moderates the properties of various herbs, enabling Ramulus Cinnamomi, Paeoniae Radix Alba and other herbs to act synergistically better and jointly regulate qi and blood. For example, during the course of bi syndrome, due to the unsmooth flow of qi and blood resulting in joint pain, sallow complexion and other conditions, the combination of Ramulus Cinnamomi, Paeoniae Radix Alba and Glycyrrhizae Radix Praeparata cum Melle can effectively improve the circulation of qi and blood, making the complexion rosy and reducing the pain.

3. Balance Yin and Yang

Anemarrhenae Rhizoma clears heat and nourishes yin, restricts the warm nature of herbs such as Ramulus Cinnamomi and Ephedrae Herba, and prevents excessive warmth and dryness from damaging yin. At the same time, it regulates the symptoms of internal heat due to yin deficiency that may occur after a long-term bi syndrome, making the formula reach a state of balance between yin and yang. For example, if a patient shows yin deficiency symptoms such as dry mouth and low fever during the treatment of bi syndrome due to overuse of warm herbs, the function of Anemarrhenae Rhizoma in clearing heat and nourishing yin can timely correct the imbalance between yin and yang and ensure the smooth progress of treatment.

4. Nourish Liver and Kidney

Although there are no herbs directly tonifying the liver and kidney in the formula, by dispelling wind-cold-damp pathogens and regulating qi and blood, it makes the meridians smooth and qi and blood sufficient, which is beneficial to the nourishment of the liver and kidney. When the liver and kidney are nourished, the muscles and bones will be strong, preventing the further development of the disease. For example, for patients with obvious liver and kidney deficiency after a long-term bi syndrome, showing symptoms such as weakness in the waist and knees, dizziness and vertigo, on the basis of using Ramulus Cinnamomi, Paeoniae Radix Alba and Anemarrhenae Decoction to dispel wind, remove dampness and regulate qi and blood, it can indirectly play a role in nourishing the liver and kidney and promoting the recovery of the disease.
