The other herbs listed have no specific effect on peripheral thyroid hormone conversion. Berberis vulgaris is used to treat respiratory conditions, and infections such as the cold and flu. Apium graveolens has been used to treat pain. Panax ginseng has been used as a stimulant, and to treat sexual dysfunction in men. Symphytum officinale has been used to treat gout, and disorders of the gastrointestinal tract. Zea mays may help treatment of skin diseases.

Example Question #21 : Care
Urtica dioica (stinging nettle) leaf is used for all of the following except __________.
Allergic rhinitis
Nutritional support
Psoriasis
Anti-inflammation
Psoriasis
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.

They will often arch backwards when crying, and will be soothed when bounced, carried, patted, or swaddled. These infants experience difficult dentition and will chew their fingers before teething.
Arsenicum album and calcarea carbonica are both more often indicated for chilly babies that are prone to anxiety, while arnica is generally given for people who have experienced some sort of dissociative shock from a physical or emotional trauma.
