You can eat some purslane in moderation during lactation. Portulaca oleracea contains a lot of potassium salt, which has a good diuretic and detumescence effect. If the lactating mother has postpartum edema, she might as well eat purslane. In addition, potassium ions in Portulaca oleracea can directly act on the blood vessel wall, dilate the blood vessel wall, prevent the arterial wall from thickening, and thus lower blood pressure.
