Ma Ya benefits
Mai Ya herb
Digestive aid
Mai Ya contains alpha and beta amylases. And starch is a mixture of sugar starch and gum starch. The glucose molecules that makeup sugar starch are connected by α-1,4 glycoside bonds and arranged in straight chains. Gum starch is crossed by several short straight chains of condensed glucose. The branched starch molecules have α-1,6 glucoside bonds in addition to α-1,4 glucoside bonds. α and β amylases can hydrolyze α-1,4 glucoside bonds but have no effect on α-1,6 glucoside bonds. β amylase can completely hydrolyze sugar starch into maltose, while α amylase breaks it down into short straight bond condensed glucose (i.e. dextrin), which can be hydrolyzed into maltose by β amylase. Thus, starch can be broken down into maltose and dextrin by the action of α and β amylases. Malt decoction seems to have a mild promotion effect on the secretion of gastric acid and pepsin.
Hypoglycemic effect
Administration of Maiya infusion orally lowered blood glucose in rabbits and normal humans. The 5% injection solution made of malt residue aqueous alcoholic precipitation product can lower the blood sugar of rabbits by 40% or more when injected with 200mg, and most of them recovered after 7 hours.

Inhibition of prolactin release
Raw Mai Ya decoction 100-200g/d orally can suppress the peak of prolactin release during sleep or methotrexate test in healthy people, which may be related to the lactation-returning effect of raw Maiya soup in women, and can make breast overflow disappear or be relieved in patients with simple breast overflow, but the peak of response to methotrexate test is not suppressed, and it is not effective in amenorrhea-lactation syndrome with an organic lesion of pituitary prolactinoma.
