(Xiao Mai / Common Wheat) Is incompatible with Han Jiao (Zanthoxyli Pericarpium) and Luobo (Raphani Fructus).
Sweet, slightly cold. Enters the Qi level of the Hand-Shaoyin Heart Meridian and Foot-Taiyin Spleen Meridian. Nourishes the Heart and tonifies the Spleen, assists the Five Zang Organs, and thickens the intestines and stomach. Eliminates irritability, thirst, and dryness of the throat; stops hematemesis and metrorrhagia. Promotes urination, consolidates deficiency sweating. Treats insomnia due to Heart heat, and bone-steaming tidal fever due to Yin deficiency. Applied externally for carbuncles, swellings, and trauma. Combined with Tongcao (Tetrapanacis Medulla), treats the five types of strangury (Wu Lin). Mixed with Haizao (Sargassum), dissipates goiter (Ying Liu). Lightly stir-fried, ground into fine powder, and taken mixed with Jingmo juice or Oujie juice to stop internal injury-induced hematemesis.
Xin Mai (New Wheat) is hot in nature, while Chen Mai (Aged Wheat) is neutral. Those produced in northern regions are superior. Removing the bran makes it warm; it tonifies deficiency and nourishes Qi. Using it with the bran eliminates irritability and heat. Stir-fried and ground, it treats diarrhea and dysentery. Xin Mai should not be used (as it stagnates Qi and aids damp-heat).

Maimiao (Wheat Sprouts)
