Peony is an alterative, analgesic, anodyne, antibacterial, anti-inflammatory, antiseptic, antispasmodic, astringent, carminative, diuretic, emmenagogue, expectorant, febrifuge, hypotensive, nervine tonic and treats women’s complaints. The root of Chinese peony has been used for over 1,500 years in Chinese medicine. It is known most widely as one of the herbs used to make 'Four Things Soup', a woman's tonic, and it is also a remedy for gynaecological problems and for cramp, pain and giddiness. (1)
In Traditional Chinese Medicine White Peony Root is called Bái Sháo白芍. Bái Sháo is bitter, sour and cool and enters the Liver and Spleen channels. Bái Sháo nourishes the Blood and regulates menses due to Blood deficiency, calms Liver Yang to alleviate pain from constrained Liver Qi or Liver and Spleen Qi disharmony due to Liver Yang rising, such as cramping and spasms (limbs and abdomen), abdominal pain from dysentery, headache and dizziness and preserves Yin by adjusting Ying & Wei levels and is used to treat vaginal discharge and spermatorrhoea.

The most important ingredient medicinally in the root is paeoniflorin, which has been shown to have a strong antispasmodic effect. It also reduces blood pressure. (3)
Paeonia lactiflora and its constituents paeoniflorin and paeonol are antiallergic and can improve IgE-induced anaphylaxis. (4)
Active constituents in Bai Shao (Paeonia lactiflora) include paeoniflorin and albiflorin. (5)
paeonia lactiflora displays both anti-inflammatory and immunomodulatory effects. (6)
The effects of paeoniflorin and albiflorin (the principal components of peony) on cytochrome P450 (CYP) 3A4 and CYP2D6 (Phase I Liver modification enzymes) were analyzed in human hepatoma and it was found that both paeoniflorin and albiflorin could regulate CYP3A4 and CYP2D6 with varying degrees. (7)
A Cochrane Collaboration Meta-analysis study supported the complementary use of herbal medicine including that of peony lactifora as paratherapy for Parkinson disease patients. (8)
