Yes, 四神汤 can be made with 薏米 (yìmǐ) and 芡实 (qiànshí) in addition to the traditional ingredients of 白术 (báizhú) and 桂枝 (guìzhī). 薏米 is believed to have a diuretic effect and help with water retention, while 芡实 is believed to tonify the spleen and regulate digestion.
家庭炒制芡实，常用的干炒法全程中小火炒10-15分钟，药用常用的麸炒法全程中小火炒8-12分钟，可根据芡实颗粒大小微调炒制时间，炒好放凉即可使用或保存。先把铁锅烧干，确保锅里没有残留水分和油星，干炒直接把芡实全部倒入冷锅；麸炒要先下麦麸，小火炒出麦香之后再倒入芡实。
