What is Rhodiola rosea? Rhodiola, or Rhodiola rosea, is a plant in the family Crassulaceae that can grow up to 3,000 meters above sea level. Dioscorides, who is known as the "father of pharmacology," wrote the book De materia medica in 77 AD. In it, he talked about the properties of this perennial plant. Rhodiola's roots, or rhizomes, are used in phytotherapy. It has antioxidant flavonoids (rhodioline, rhodiosine, rhodaline, and kaempferol) and monoterpenes (rosaridine) that reduce inflammation and boost the immune system. But the phenylpropanoids in Rhodiola, such as rosavins, are mostly responsible for the plant's effects. Rhodiola rosea also has chemicals called phenylethanoids, which give roses their smell.
