Chinese sweet leaf

•Last Updated: September 28 2022

Rubus suavissimus (Chinese sweet leaf) is a plant whose leaves are used to brew a sweetened tea, and it is currently thought to be a decent weight loss aid in part due to suppressing the formation of body fat and in part due to its sweetness helping with food cravings.

Summary

Rubus suavissimus is a plant in the raspberry family which contains a variety of natural sweeteners (the suaviosides) somewhat similar to the molecules in stevia, another naturally sweet plant. In part due to the sweetness aiding somebody psychologically on a diet, the potential suppressive effects on weight gain seen in rats suggests that this tea may have anti-obese properties; more research would be needed to see if there is any promise for this herb though.

Beyond that, the tea appears to be traditionally used to help with symptoms of sickness (usually to attenuate allergies, relieve cough, and increase mucus production and aid in its clearnace from the body). The claims on cough, fever, and mucus have not yet been evaluated and while there appear to be some preliminary evidence to support a reduction in allergies the one accessible human study has failed to find such an effect.
