Example Question #72 : Ethics, Processing, And Care

Urtica dioica (stinging nettle) leaf is used for all of the following except __________.

Possible Answers:

Nutritional support

Allergic rhinitis

Anti-inflammation

Psoriasis

Correct answer:

Psoriasis

Explanation:

Urtica dioica (stinging nettle) leaf extract contains antagonists of the histamine-1 (H(1)) receptor, thus decreasing symptoms of allergic rhinitis and sinusitis. Nettle leaf extract also contains factors that inhibit mast cell tryptase, preventing degranulation and release of a host of pro-inflammatory mediators that cause the symptoms of hay fevers, and inhibits cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), and hematopoietic prostaglandin D(2) synthase. As a nutritive, nettle leaf is an excellent source of vitamin A, vitamin C, iron, and calcium. Nettle leaf has shown no benefit in treatment of psoriasis, though it may help to correct any underlying nutritional deficits.
