- Ensuring a guaranteed minimum level of a specific active constituent per dose (Correct answer)
- Certifying herbs as safe by the FDA

- Vitamin C

Echinacea's immune-stimulating properties can counteract immunosuppressant medications used after organ transplants or for autoimmune diseases.
Question 7: A decoction differs from a standard infusion (tea) in which important way?
- Decoctions use cold water and infusions use hot water
- Decoctions simmer plant material for 15–30 minutes while infusions steep briefly in hot water (Correct answer)
- Decoctions are always alcoholic preparations
- Infusions extract roots while decoctions extract leaves
Correct answer: Decoctions simmer plant material for 15–30 minutes while infusions steep briefly in hot water
Decoctions apply prolonged heat to break down tough cell walls of roots, bark, and seeds that a brief steep cannot penetrate.
