A nurse working in an alternative therapy clinic is assisting in the care of a client who has elevated cholesterol levels. Which of the following herbs should the nurse recommend?

A. Valerian root: Valerian root is primarily used for its sedative and anxiolytic effects, such as promoting sleep or reducing anxiety. It does not have lipid-lowering properties and is not indicated for managing elevated cholesterol levels. B. Aloe: Aloe is commonly used for gastrointestinal issues, such as constipation or skin conditions when applied topically. It does not significantly affect serum lipid profiles or cholesterol management. C. Saw palmetto: Saw palmetto is mainly used to support urinary function in men with benign prostatic hyperplasia. It has no clinically significant effect on cholesterol levels and is not recommended for hyperlipidemia. D. Garlic: Garlic has demonstrated lipid-lowering effects by reducing total cholesterol and low-density lipoprotein (LDL) levels. It can be used as an adjunct therapy for clients with elevated cholesterol to help improve cardiovascular health.
