Answer to Question 1

Echinacea is a nonspecific stimulator of the innate (nonspecific) immune system. It stimulates phagocytosis and effector cell activity. There is an increased release of tumor necrosis factors and interferons from macrophages and T lymphocytes, which increases the body's resistance to bacterial and viral infection. It may have anti-inflammatory effects by inhibiting hyaluronidase, a potent inflammatory. Aloe gel has been marketed for topical use to treat pain, inflammation, and itching and as a healing agent for sunburn, skin ulcers, psoriasis, and frostbite. Chamomile is used as a digestive aid for bloating and as an antispasmodic and anti-inflammatory in the GI tract, an antispasmodic for menstrual cramps, an anti-inflammatory for skin irritation, and a mouthwash for minor mouth irritation or gum infections. Ginger has been used for centuries to alleviate nausea and vomiting from a variety of causes. It is thought to act as an antiemetic by increasing gastroduodenal motility and by blocking serotonin receptors that, when stimulated, may trigger nausea and vomiting.
