Aucklandia Lappa Extract
Also known as: Radix Aucklandiae, Mok-hyang, Aucklandia lappa Decne., *Aucklandia lappa*
Overview
Aucklandia lappa, commonly known as Radix Aucklandiae or Mok-hyang, is a perennial herb extensively utilized in traditional oriental medicine for its potential health benefits. Originating from the mountainous regions of Yunnan and Sichuan in China, the herb is known for its anti-inflammatory, anti-ulcer, and antimicrobial properties. While in vitro studies suggest notable pharmacological effects, high-quality clinical trials investigating its efficacy in humans remain scarce, resulting in a need for further research. Traditionally, it has been employed to treat gastrointestinal issues and stress-related ailments. The extract is available in various forms, commonly in decoctions or other herbal formulations.
Benefits
Research indicates that Aucklandia lappa extract possesses substantial anti-inflammatory and antioxidative properties, effectively reducing pro-inflammatory mediators such as COX-2, IL-6, IL-1β, and TNF-α in cellular models. Furthermore, it demonstrates antimicrobial activity against a wide range of plant pathogens. Traditionally, it has been associated with the alleviation of abdominal pain, vomiting, diarrhea, and the treatment of stress-induced gastric ulcers. While the anti-inflammatory potential appears significant, clinical trials in human populations are necessary to confirm these benefits and establish clinically relevant effect sizes.
How it works
Aucklandia lappa extract functions by modulating key biological pathways involved in inflammation. It suppresses the NF-κB and MAPK pathways, which play crucial roles in inflammatory responses, and activates the Nrf2/HO-1 pathway, contributing to its antioxidant effects. The extract is known to target molecular constituents such as iNOS and pro-inflammatory cytokines (e.g., IL-6, TNF-α), ultimately leading to decreased inflammatory responses. Further research is essential to elucidate the full spectrum of its mechanisms and bioavailability.
Side effects
Aucklandia lappa is traditionally regarded as safe, though specific and comprehensive safety data are underrepresented due to the lack of formal clinical trials. Currently, common side effects are not well-documented, and any uncommon or rare side effects are also unknown. There are speculative risks of drug interactions with anti-inflammatory medications and other herbal supplements, but no formal contraindications have been established. Special caution may be warranted for pregnant or lactating individuals, as adequate studies have not been conducted in these populations.
Dosage
Dosage recommendations for Aucklandia lappa extract are not well-defined, necessitating reliance on traditional practices. Currently, the minimum effective dose has yet to be established through human studies, while optimal dosage ranges remain unspecified. Ethanol extracts and decoctions are commonly used forms; however, specific dosing guidelines are currently absent. The maximum safe dose hasn't been determined, underscoring the need for further research to establish proper dosing regimens and timing considerations, alongside understanding absorption factors.
