Sweet Tea (Rubus suavissimus)


Consumed mainly as health-promoting herbal tea in Southwestern China and popular in Japan as a natural remedy against seasonal allergies, Sweet Tea leaf is rich in rubusoside and polyphenols with beneficial effects of alleviating obesity, Type 2 diabetes and asthma.

Traditional Use of Sweet Tea (Rubus suavissimus)

  • Sweet Tea plant thrives like rose bushes (a.k.a. Chinese blackberry), wide spread at 500~1000m altitude
    in mountains in Southwest China.
  • 115 times sweeter than table sugar but low in calories, Sweet Tea has a long history of use as natural
    sweetener and folk medicine for various health benefits such as weight loss, diabetes and kidney

Modern Research on Sweet Tea (Rubus suavissimus)

  • Later discovered by a joint study of Chinese and Japanese scientists in the 1990’s, Sweet Tea contains a diterpene glycoside called rubusoside that has demonstrated various important biological functions with implications in alleviating allergy/asthma, obesity, diabetes, and cancer.
  • Research also revealed that Sweet Tea extract can suppress allergic reactions by inhibiting IgE-mediated histamine release from mast cells, prostaglandin E2 synthesis and cutaneous anaphylaxis.
  • Studies show that Sweet Tea leaf  extract could inhibit NF-κB and R-amylase, which is closely related to
    glucose metabolism, and highly potent against angiogenesis by inhibiting both vascular endothelial
    growth factor (VEGF) and platelet-derived growth factor receptors in endothelial and smooth muscle cells.
