Glehnia Root Extract

Also known as: Bei sha shen, Hamabofu, American silvertop root, *Glehnia littoralis*

Overview

Glehnia littoralis, commonly known as Bei sha shen, is a perennial plant native to Asia, particularly along the coasts of China and Japan. The root of this plant is utilized in traditional medicine for various health issues, particularly respiratory and digestive conditions such as bronchitis and fevers. Chemical compounds found in Glehnia root include coumarins, polysaccharides, lignans, and flavonoids, which are associated with antioxidant, anti-inflammatory, and potential antitumor activities. Despite its historical usage, current research on Glehnia littoralis predominantly consists of in vitro and animal studies, with very few clinical trials conducted in humans, leading to limited evidence regarding its safety and efficacy.

Benefits

Studies indicate that *Glehnia littoralis* extract may exhibit antitumor properties, as an in vitro study demonstrated induction of apoptosis in Hep3B liver cancer cells. Additionally, animal studies suggest anti-inflammatory effects; however, the evidence remains preliminary and not robust enough to support significant health claims in humans. Specific populations that may benefit have not been distinctly identified, and the effect sizes are not quantified due to the lack of quality human trials. Overall, it is important to emphasize that while some potential benefits exist, they are not clinically substantiated.

How it works

The principal mechanism of action associated with *Glehnia littoralis* is believed to involve pathways related to apoptosis, particularly in the context of its antitumor effects. However, the specific biological pathways and molecular targets in the human body are not well defined. Additionally, there is limited understanding of how it interacts with human physiological systems, and bioavailability has not been investigated in human studies.

Side effects

Currently, the safety profile of *Glehnia littoralis* is considered generally safe based on traditional uses; however, documented side effects are sparse and largely unknown, given the lack of empirical studies. Common and uncommon side effects have not been established in scientific literature, and it remains unclear if there are any rare adverse reactions. Potential interactions with medications have yet to be thoroughly studied. Due to insufficient research, pregnant or breastfeeding women are advised to consult their healthcare providers before using this supplement, considering the absence of conclusive safety data.

Dosage

There are currently no established guidelines for the minimum effective dose, optimal dosage ranges, or maximum safe doses of *Glehnia littoralis*. Typically, the root is consumed as an extract, but specifics regarding timing and administration are not well documented. Factors affecting absorption and necessary cofactors for potential efficacy remain unknown, underscoring the need for further research to delineate appropriate dosing guidelines.
