The Efficacy and Functions of Prepared Rehmannia Root

Rehmannia glutinosa (Shu Di Huang), as a traditional Chinese medicinal herb, has multiple functions and benefits. Rehmannia glutinosa can nourish the blood and treat deficiency syndromes because its sweet and warm nature with a moist texture helps replenish yin, enrich essence, and promote blood production. It shows significant therapeutic effects for symptoms such as sallow complexion due to blood deficiency, dizziness, and palpitations. Rehmannia glutinosa can prevent cardiovascular diseases because it reduces the formation of blood clots within blood vessels, thus preventing diseases caused by thrombosis, and it also has certain antihypertensive effects. Rehmannia glutinosa nourishes the kidneys and enriches kidney yin; it can elevate the levels of T4 and aldosterone in plasma and improve symptoms such as liver and kidney yin deficiency, and soreness and weakness of the waist and knees. Additionally, Rehmannia glutinosa has multiple other functions, including clearing heat and cooling blood, nourishing the kidneys and liver, strengthening deficiency syndromes and invigorating qi, nourishing the heart and calming the mind, and moistening the intestines to relieve constipation.
