sharp-leaf galangal
Alpinia oxyphylla
Alpinia oxyphylla, also known as "Yizhi" in Traditional Chinese Medicine, is a plant traditionally used for various purposes but lacks specific traditional uses documented. Scientific evidence suggests potential benefits such as reducing calf diarrhea incidence and improving gut microbiota composition through the use of polyherbal mixtures containing Alpinia oxyphylla. Additionally, studies indicate that purified polysaccharide fractions from this plant may extend lifespan and enhance antioxidant activities in worms, while sesquiterpenoids identified from its fruits show potential antidiabetic activity, though further research is needed to confirm these findings. The sulfated derivative of a polysaccharide from Alpinia oxyphylla has shown robust inhibitory activity against colorectal cancer cell lines. No major safety concerns or recorded drug interactions have been noted for this plant.
