Sichuan Teasel Root Extract
Also known as: Sichuan Teasel Root, Xu Duan, Dipsacus asper
Overview
Sichuan Teasel Root, scientifically known as *Dipsacus asper*, is an herbal supplement derived from the root of a plant traditionally used in Chinese medicine. It is primarily valued as a kidney yang tonic and for its applications in musculoskeletal health. Historically, it has been employed to support joint health, alleviate symptoms of arthritis, reduce lower back pain, and aid in recovery from trauma injuries. Additionally, it finds use in addressing certain gynecological issues such as menorrhagia and leucorrhea. Phytochemical analyses have identified bioactive compounds within the root, including iridoids and phenolic compounds, which are believed to contribute to its therapeutic effects. While traditional use is extensive, high-quality clinical evidence from robust human trials or meta-analyses is sparse, with most current data stemming from in vitro studies, animal research, or historical accounts.
Benefits
Sichuan Teasel Root is primarily recognized for its traditional use in supporting joint health and reducing inflammation and pain associated with arthritis and musculoskeletal injuries. While strong clinical evidence from human trials is lacking, its traditional application suggests benefits for individuals experiencing chronic joint or bone disorders, particularly those linked to kidney and liver deficiencies in Traditional Chinese Medicine (TCM) theory. In vitro studies have also indicated potential antimicrobial activity against various bacterial and yeast strains, suggesting a broader range of potential applications beyond musculoskeletal support. However, it is important to note that no high-quality randomized controlled trials or meta-analyses exist to quantify effect sizes or confirm these benefits in humans. Traditional use suggests that benefits may manifest with consistent dosing over several weeks to months.
How it works
Sichuan Teasel Root contains bioactive compounds such as iridoids and polyphenols, which are known for their anti-inflammatory and antioxidant properties. These compounds are believed to modulate immune responses and may inhibit microbial growth, as demonstrated in in vitro studies. In the context of Traditional Chinese Medicine (TCM), *Dipsacus asper* is thought to act on the kidney and liver channels, which are associated with musculoskeletal and hormonal regulation. This traditional perspective suggests a systemic influence on the body's balance and function. However, the exact mechanisms of action in humans, including absorption and bioavailability, are not yet well characterized by modern scientific research.
Side effects
Sichuan Teasel Root is generally considered safe based on its long history of traditional use, with no significant contraindications or common side effects widely reported in available literature. However, it is crucial to note that there is a significant lack of high-quality clinical safety data from rigorous human trials. This means that potential adverse effects, their severity, and frequency are not well documented or understood through modern pharmacovigilance. No known significant drug interactions have been identified from independent clinical studies. Due to the limited clinical safety data and absence of robust research, caution is advised, especially for individuals with pre-existing conditions or those taking other medications. Comprehensive safety warnings are difficult to provide without more extensive clinical research.
Dosage
There is no standardized dosing for Sichuan Teasel Root established through clinical trials. Traditional dosing varies widely, and commercial extracts typically suggest a dosage of 30-40 drops (approximately 1.5-2 mL) taken three times daily. These extracts are commonly prepared with a concentration ratio of 1:4, using solvents such as alcohol, glycerin, or water. It is important to understand that these recommendations are based on traditional use and manufacturer guidelines, not on evidence from controlled clinical studies. Data regarding the maximum safe dose, potential upper limits, or any required cofactors for optimal absorption and efficacy are currently unavailable. Users should exercise caution and consult with a healthcare professional before starting supplementation.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC7020454/ – This study conducted phytochemical analysis of *Dipsacus fullonum* roots, identifying iridoids and phenolic compounds. It also demonstrated in vitro antimicrobial activity against various bacteria and yeasts. The research provides insights into the chemical constituents and potential biological activities, but it is an in vitro study and not directly on *Dipsacus asper* or human clinical outcomes.
