Suma (Pfaffia paniculata), often referred to as "Brazilian ginseng," has a long history of use in traditional South American herbal medicine, especially in Brazil. It has been used as a general tonic and adaptogen, purported to increase physical strength, stamina, and energy. In folk medicine, suma root is sometimes recommended for athletes or individuals with physically demanding lifestyles, which relates to its support of the muscular system. This traditional use is based on anecdotal reports and ethnobotanical surveys rather than rigorous clinical trials.

Scientific research on suma's effects on muscle strength or function is limited. Some in vitro and animal studies suggest it contains compounds such as pfaffic acids, saponins (notably pfaffosides), and ecdysteroids, which may have adaptogenic and anabolic effects. For example, ecdysteroids are plant steroids that have shown some potential to promote protein synthesis in animal models, theoretically benefiting muscle tissue. However, robust human clinical trials are lacking, and the evidence doesn't conclusively support suma’s efficacy for enhancing muscle health or performance.

In summary, the use of suma to support the muscular system is primarily justified by traditional use and some preliminary scientific rationale, but there is insufficient high-quality evidence to strongly endorse its benefits for muscle strength or function in humans.
