Uses: Chamomile is often used in the form of a tea as a sedative.

Reactions: Allergic reactions can occur, particularly in persons allergic to ragweed. Reported reactions include abdominal cramps, tongue thickness, tightness in the throat, swelling of the lips, throat and eyes, itching all over the body, hives, and blockage of the breathing passages. Close monitoring is recommended for patients who are taking medications to prevent blood clotting (anticoagulants) such as warfarin.

2. Echinacea

Uses: Largely because white blood cells in the laboratory can be stimulated to eat particles, Echinacea has been touted to be able to boost the body’s ability to fight off infection.

S/E : unpleasant tastel, liver toxicity.

C/I: ketaconazole, leflunomide (Arava), methotrexate (Rheumatrex), isoniazide (Nizoral).

3. St. John’s Wort

Uses: depression, anxiety, and sleep disorders. It is technically known as Hypericum perforatum.

5. Feverfew

Uses: Most commonly used for migraine headaches.

Reactions: Feverfew can cause allergic reactions, especially in persons who are allergic to chamomile, ragweed, or yarrow. Nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen (Advil), naproxen (Aleve) or Motrin) can reduce the effect of feverfew. A condition called “postfeverfew syndrome” features symptoms including headaches, nervousness, stiffness, joint pain, tiredness, and nervousness. Feverfew can impair the action of the normal blood clotting element (platelets). It should be avoided in patients taking medications to prevent blood clotting (anticoagulants) such as warfarin (Coumadin).

6. Ginko Biloba

Uses: This herb is very popular as a treatment for dementia (a progressive brain dysfunction) and to improve thinking.

Reactions: Mild stomach upset and headache have been reported. Ginko seems to have blood thinning properties. Therefore, it is not recommended to be taken with aspirin, nonsteroidal anti-inflammatory drugs (Advil), naproxen (Aleve) or Motrin), or medications to prevent blood clotting (anticoagulants) such as warfarin (Coumadin). Ginko should be avoided in patients with epilepsy taking seizure medicines, such as phenytoin (Dilantin), carbamazepine (Tegretol), and phenobarbital.

7. Ginseng

Uses: Ginseng has been used to stimulate the adrenal gland, and thereby increase energy. It also may have some beneficial effect on reducing blood sugar .in patients with diabetes mellitus. (Dr. Miller emphasized that there is substantial variation in the chemical components of substances branded as “Ginseng.”)

Reactions: Ginseng can cause elevation in blood pressure, headache, vomiting, insomnia, and nose bleeding. Ginseng can also cause falsely abnormal blood tests for digoxin level. It is unclear whether ginseng may affect female hormones. Its use in pregnancy is not recommended. Ginseng may affect the action of the normal blood clotting element (platelets). It should be avoided in patients taking aspirin, nonsteroidal antiinflammatory drugs (such as ibuprofen (Advil), naproxen (Aleve) or Motrin), or medications to prevent blood clotting (anticoagulants) such as warfarin (Coumadin). Ginseng may also cause headaches, tremors, nervousness, and sleeplessness. It should be avoided in persons with manic disorder and psychosis.

Reactions: This herb may affect the action of the sex hormone testosterone, thereby reducing sexual drive or performance. Dr. Miller states that “While no drug-herb interactions have been documented to date, it would be prudent to avoid concomitant use with other hormonal therapies (e.g., estrogen replacement therapy and oral contraceptives…”)
