Pinellia Ternata Rhizome Extract
Also known as: Banxia (Chinese), Hange (Japanese), Banha (Korean), *Pinellia ternata*
Overview
*Pinellia ternata* is a plant utilized in traditional medicine, particularly its rhizome, which is dried and processed for therapeutic applications. It has been primarily employed to treat nausea, vomiting, and respiratory conditions. The rhizome contains an array of bioactive compounds, including alkaloids, polysaccharides, and phenylpropanoids, which are thought to contribute to its medicinal properties. While growing evidence highlights its use, particularly alongside 5-HT3 receptor antagonists for chemotherapy-induced nausea and vomiting (CINV), there is a need for more high-quality clinical trials to establish its efficacy and safety comprehensively. Currently, the research is based on both traditional practices and emerging clinical studies, but systematic reviews are starting to form a more conclusive understanding of its clinical relevance.
Benefits
Evidence-based benefits of *Pinellia ternata* include: 1) significantly improved management of CINV when used in combination with 5-HT3 receptor antagonists, showing a relative risk (RR) of 1.46 (95% CI = 1.37-1.57, p < 0.00001), with noted enhancements in appetite and quality of life primarily in chemotherapy patients. 2) Potential anti-inflammatory effects in alleviating acute lung injury, as indicated by clinical studies. These findings suggest its therapeutic potential, particularly in populations undergoing chemotherapy or experiencing respiratory inflammation, yet the overall evidence quality needs further rigorous examination.
How it works
*Pinellia ternata* acts through various biological pathways, affecting both the immune and nervous systems. The bioactive compounds interact with inflammatory pathways to reduce nausea and vomiting and may alleviate respiratory inflammation. Specific molecular targets include lectins that influence inflammatory mediators and cytochrome P450 enzymes, demonstrating a multifaceted approach in its therapeutic mechanisms. Traditional decoction methods may improve its bioavailability, enhancing its physiological effects.
Side effects
The safety profile of *Pinellia ternata* is generally favorable when used properly, but raw forms contain toxic lectins that necessitate processing to mitigate risks. Common side effects are not well-documented, though there is lower incidence when used in conjunction with 5-HT3 receptor antagonists. Potential gastrointestinal upsets may occur if not adequately processed, with rare side effects largely unreported. Caution is advised regarding interactions with medications metabolized by cytochrome P450 enzymes. Pregnant or breastfeeding women are urged to consult healthcare providers prior to use.
Dosage
Recommended dosages of *Pinellia ternata* vary based on traditional usage and specific conditions treated, as a minimum effective dose has not been firmly established. Typically used in traditional decoctions or processed extracts, the dosage may adjust depending on treatment goals. There is no defined maximum safe dose; however, caution is advised with high dosage intake. *Pinellia ternata* is often consumed as needed for symptoms like nausea, with absorption influenced by traditional preparation methods.
