Iranian researchers assessed the blood pressure of 48 diabetic adults and then gave them either a daily cup of yogurt or yogurt with purslane seeds (10 grams, about one-third of an ounce). After 5 weeks, the groups switched treatments (a crossover trial). While taking purslane, participants’ blood pressure declined significantly and participants lost weight while taking purslane — about a pound in 5 weeks.
