There are some herbs and vitamins that you can’t take together
In every issue of Herbs for Health, professionals from a variety of health-care fields answer your questions about using medicinal herbs. Medical doctor Robert Rountree and herbalist Rosemary Gladstar respond for this issue.
Q. Are there any herbs and vitamins that can’t be taken together? I take coenzyme Q-10 (90 mg) for my mitral valve prolapse, dong quai root (1,130 mg) for female problems, and kava (425 mg) for stress, along with vitamin C, B-complex, and beta-carotene. Is it safe to combine all of these? Also, can you suggest a good reference book?
A. There are some herbs and vitamins that you can’t take together. In general, the more concentrated or potent the extract, the more you begin to get a druglike effect, which means a higher potential for side effects. However, I don’t have any reason to suspect a toxic interaction for any of the vitamins or herbs that you have listed.
Two books I have found to be very helpful are Herbal Prescriptions for Better Health by Donald Brown, N.D., and The Healing Power of Herbs by Michael Murray, N.D. (both published by Prima in 1996).
A. The particular combination of herbs and vitamins you are taking in conjunction with your medication should not cause any adverse reactions or side effects.
However, one does need to follow sensible guidelines when combining herbs, vitamins, and allopathic medication, not only to avoid potentially ineffective or harmful combinations, but to maximize the benefit from each.
On occasion I’ve heard of or witnessed certain herbal combinations that cause unpleasant results or side effects, but often the reaction has turned out to be idiosyncratic, or an individualized response.
Though no hard and fast rules apply for what not to combine, there are endless amounts of good information available on herbs and vitamins that do combine well. For an exceptional listing of trustworthy herb books, request the American Botanical Council’s Herbal Education Catalog, which contains more than 300 books, along with audio and video tapes, computer software, and special reports. The American Botanical Council can be reached at (800) 373-7105 or by writing to P.O. Box 201660, Austin, Texas 78720. Catalogs are $2.50 or free with an order.
One of my favorite books is The New Holistic Herbal (Element, 1991) by David Hoffmann.
Q. I have gastric erosion and inflammation due to gastroesophageal reflux (GERD). I am currently taking anti-spasmodic medication and prescription antacids, and am already experiencing side effects. I would like to request information on the following herbs that have been recommended as antispasmodics, anti-inflammatories, or digestive aids: fennel, feverfew, bog asphodel, mandrake, rosemary, and valerian.

A. Gastroesophageal reflux (GERD) is a condition where the lower esophageal sphincter—a ring of muscles separating the esophagus from the stomach—has become lax and no longer does its job of preventing stomach acid from refluxing, or reflowing, back up into the esophagus. When this happens it results in a sensation called heartburn. The lining of the esophagus and upper-stomach opening lacks the thick mucus coating that protects the stomach walls from acid, so it is highly susceptible to erosion and ulcers.
The most important dietary consideration is to avoid agents that relax this sphincter. These include caffeine, alcohol, and carminatives (herbs that relieve gas and cramps) such as peppermint and fennel.
To treat the erosion and inflammation, I recommend L-glutamine, which can be taken in the pure powder form, 5 g to 10 g daily, or as cabbage juice, 2 ounces to 4 ounces daily.
In addition, deglycyrrhizinated licorice has been shown to be very effective for this condition. It works best when taken as tablets that are chewed thoroughly right after meals. Other agents that you may find helpful are aloe vera juice, marsh mallow root (Althaea officinalis), slippery elm (Ulmus rubra), and umeboshi plum paste (Prunus salicina).
A. While antacids are helpful and often recommended for GERD, I would suggest natural alternatives. Hydrochloric acid (HCA) supplements are available at most natural food stores. The protocol for determining the correct dosage of HCA is detailed in Natural Alternatives to Over-the-Counter and Prescription Drugs by Michael Murray, N.D. (William Morrow, 1994). Naturopathic doctors often recommend using pancreatin (pancreatic enzymes produced from animal sources) in addition to HCA to aid digestion.
Of the herbs you listed, I would caution against the use of mandrake (Mandragora officinarum) because of its potential toxicity, and I question the effectiveness of bog asphodel (Asphodelus spp.), feverfew (Tanacetum parthenium), and rosemary (Rosmarinus officinalis), all good herbs but not specific for your situation.
I suggest nontoxic antispasmodics, herbs that aid digestion, and herbs that soothe the irritated tissue of the esophagus. Valerian is a good choice; it is a powerful antispasmodic and helps relax the muscles. Some people, however, experience a stimulating rather than relaxing effect, so take note. Fennel is a good digestive aid and can be used effectively in your situation. I suggest blending it with the gentle, calming chamomile (Matricaria recutita). Chamomile is an effective anti-inflammatory, digestive aid, and digestive nervine (relaxes the nervous system). For chronic inflammation, try slippery elm, which is a nutritive digestive aid and one of the best herbs for soothing irritated tissue. Mix it into a drink with aloe vera juice which also will aid digestion and soothe irritated mucous membranes.
