The effects and indications of white peony root：

1. Nourishing Blood and Regulating Menstruation: White peony root nourishes liver blood and regulates the Chong and Ren meridians, improving symptoms caused by blood deficiency such as sallow complexion, dizziness, palpitations, pale lips and nails, scanty menstruation, and delayed menstruation. It is an essential medicine for regulating menstruation in gynecology.

It is often combined with angelica, rehmannia, and chuanxiong to form Siwu Tang, a basic formula for nourishing blood in traditional Chinese medicine, suitable for menstrual disorders due to blood deficiency and postpartum weakness. Modern research also shows that paeoniflorin in white peony root promotes hematopoiesis and regulates endocrine function.

2. Soothing the Liver and Relieving Pain: White peony root soothes the liver, relieves spasms, harmonizes the liver and spleen, and alleviates rib pain, abdominal pain, irritable bowel syndrome, dysmenorrhea, and cramps in the hands and feet caused by liver qi stagnation or blood deficiency with liver hyperactivity.

Its active ingredient, paeoniflorin, can inhibit excessive smooth muscle contraction. It is often combined with licorice root to form the Paeoniae Radix Alba and Glycyrrhizae Radix et Rhizoma Decoction, widely used to relieve acute and chronic pain such as gastrointestinal spasms and calf muscle spasms.

3. Astringent and Antiperspirant: Paeoniae Radix Alba astringes Yin and is suitable for spontaneous sweating (sweating during the day without activity) and night sweats (sweating after falling asleep at night).

Spontaneous sweating is often due to superficial deficiency and is often combined with Astragalus and Atractylodes macrocephala, such as in the Jade Screen Powder. Night sweats are often due to Yin deficiency and excessive fire, and are often combined with Oyster Shell, Wheat Germ, and Rehmannia glutinosa, such as in the Oyster Shell Powder or the Angelica Six-Yellow Decoction.

It has a good auxiliary effect in improving menopausal hot flashes and excessive sweating, and night sweats caused by chronic wasting diseases such as tuberculosis.

4. **Suppressing Liver Yang:** White peony root nourishes liver yin and suppresses excessive liver yang, making it suitable for headaches, dizziness, tinnitus, irritability, and restlessness caused by excessive liver yang. It is commonly seen in hypertension, nervous headaches, and anxiety.

It is often used in combination with Uncaria rhynchophylla, Haliotis diversicolor, and Gastrodia elata, such as in Gastrodia elata and Uncaria rhynchophylla decoction or Zhengan Xifeng decoction, exerting a sedative and hypotensive effect by regulating the nervous system.

5. **Other Modern Pharmacological Effects:**
**Immune Regulation:** White peony polysaccharides and total glycosides can regulate T-cell function and inhibit excessive immune responses, making them useful as adjunctive therapies for autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus.

**Liver Protection:** Paeoniflorin can reduce hepatocellular damage, lower transaminase levels, and slow the progression of liver fibrosis, offering some protection against chronic hepatitis and alcoholic liver disease.

Anti-inflammatory and antioxidant: Rich in phenolic compounds, it can scavenge free radicals, reduce oxidative stress, and help delay aging and prevent atherosclerosis.
