Chinese Mountain Ant, often referred to as "Polyrhachis vicina Roger," has a long history of use in Traditional Chinese Medicine (TCM). In TCM, it is considered a tonic that purportedly enhances vitality, increases stamina, and supports the body’s ability to cope with stress, which has led to claims that it can support adrenal function. However, these uses are rooted primarily in traditional beliefs and empirical observations rather than modern scientific validation.

The rationale in TCM for using Chinese Mountain Ant relates to its supposed adaptogenic properties, meaning it helps the body adapt to various stresses, including those that might tax the adrenal glands. Adrenal glands are responsible for producing hormones like cortisol that help manage stress responses. However, there is a lack of robust scientific studies or clinical trials specifically investigating the direct effects of Chinese Mountain Ant or its extracts on adrenal gland function in humans or animals. The available evidence is mostly anecdotal or based on traditional usage patterns.

In summary, while Chinese Mountain Ant is traditionally believed to support vitality and possibly adrenal health, there is minimal to no scientific evidence directly supporting these claims. Therefore, its use for adrenal gland support should be considered traditional with weak evidence (rating: 1).
