Aerva lanata, commonly known as mountain knotgrass, is a plant widely used in traditional systems of medicine such as Ayurveda and folk medicine in India and Africa. Its primary traditional uses include support for urinary tract disorders, kidney stones, and as a diuretic, rather than for premenstrual syndrome (PMS). However, in some ethnobotanical records, Aerva lanata has been cited as part of herbal mixtures or remedies used by traditional healers to address “female complaints” or menstrual irregularities, which may indirectly involve PMS symptoms such as cramps or general discomfort. It is important to note that these uses are based on local traditional knowledge rather than systematic clinical studies.

To date, there is little to no direct scientific research assessing the efficacy of Aerva lanata specifically for PMS. Most pharmacological studies on Aerva lanata focus on its diuretic, anti-inflammatory, and antioxidant properties, as well as its potential in treating kidney stones and urinary disorders. While these properties might theoretically contribute to relief from some PMS symptoms (such as bloating or mild inflammation), there is no clinical evidence directly supporting its use for PMS. Thus, the use of Aerva lanata for PMS is justified more by tradition than by scientific validation, and the evidence supporting this use is very weak.
