Spilanthes
Also known as: Toothache plant, Paracress, *Spilanthes acmella*
Overview
*Spilanthes acmella* is a flowering plant indigenous to tropical regions, favored in traditional medicine for its analgesic and anti-inflammatory properties. The plant is renowned for its bioactive compounds, particularly N-alkylamides, which may influence hormone levels and pain perception. Although it is primarily used within Ayurvedic practices, the body of research on its efficacy is still developing, with many studies focused on animal models and limited human trials. As such, while its applications are promising, they are not fully supported by high-quality evidence from large-scale human studies.
Benefits
The potential benefits of *Spilanthes acmella* include a possible increase in testosterone levels, especially in young men; however, evidence remains mixed, with some studies indicating significant variations among individuals. Additionally, it showcases analgesic and anti-inflammatory effects, which cluster around pain management. The strongest evidence currently stems from small-scale randomized controlled trials, yet the variability in effect size and the lack of large cohort studies emphasize the need for further research to solidify these claims.
How it works
*Spilanthes acmella* may exert its effects via mechanisms involving hormone regulation, particularly related to testosterone levels, and influencing pain perception pathways. The biocompound N-alkylamides is thought to interact with various targets in the endocrine system. However, comprehensive understanding of its absorption and bioavailability remains undeveloped, necessitating additional study.
Side effects
Overall, *Spilanthes acmella* is generally deemed safe, with side effects largely undocumented due to the limited nature of human research. Specific risks involve potential interactions with hormonal therapies. Caution is particularly advised for individuals who are pregnant or breastfeeding due to inadequate safety data. There is also concern for those with hormonal imbalances, warranting attentiveness to individual responses in these populations. Uncommon and rare side effects have not been reported, reflecting a need for more rigorous investigations into the safety profile of this herb.
Dosage
While optimal dosage ranges for *Spilanthes acmella* have not been firmly established, it is commonly administered in extracts and capsules, and the effective doses can vary widely. Conclusive recommendations for timing or specific forms of administration are yet to be defined. Additionally, maximum safe doses are not outlined, indicating a lack of consensus in the available literature. Hence, further studies are required to establish clearer dosing guidelines.
