What side effects this plant can have?
This plant can cause abdominal pain and may lead to dangerous complications due to its potent blood sugar lowering effect in people with diabetes. While it is often used to manage a high cholesterol level, its physiological impact can be unpredictable if not monitored by a professional. Users should be cautious as the herb can interact with medications used to treat liver infections. Careful supervision is necessary to prevent hypoglycemia or other metabolic imbalances.
According to a study published by "Phytomedicine : international journal of phytotherapy and phytopharmacology", Swertia chirayita is used in traditional Tibetan medicine for the treatment of liver infections, inflammation, abdominal pain, and bacterial infection. Two main xanthones, bellidifolin (1) and swerchirin (2), were isolated from the petroleum ether (PE) and ethyl acetate fractions of the whole plants. These xanthones inhibit the production of pro-inflammatory cytokines interleukin-6 (IL-6) and TNF-α in LPS-stimulated RAW 264.7 murine macrophages. Xanthone 1 also potently inhibits the production of prostaglandin E2 (PGE2) by suppressing the protein expression of cyclooxygenase-2 (COX-2). Furthermore, xanthone 1 attenuates the phosphorylation of c-Jun N-terminal kinases (JNk), extracellular signal-regulated kinase (ERK), and p38 MAPKs in a concentration-dependent manner. Compound 1 specifically suppresses the phosphorylation of the inhibitor κB kinase-β (IKK-β), Akt, and the p65 subunit of nuclear factor-kappaB (NF-κB).
The main side effects this plant can have are shown in the list below.
- abdominal pain
- blood sugar lowering effect
