The laxatives most frequently used world-wide come from plants. Herbal laxatives are either bulk-forming or stimulating. Bulk-forming laxatives come from plants with a high fiber and mucilage content that expand when they come in contact with water; examples include psyllium, flaxseed, and fenugreek. As the volume in the bowel increases, a reflex muscular contraction occurs, stimulating a bowel movement. These mild laxatives are best suited for long-term use in people with constipation.¹

Aloe vera juice has anti-inflammatory activity and been used by some doctors for people with UC. In a double-blind study of people with mildly to moderately active ulcerative colitis, supplementation with aloe resulted in a complete remission or an improvement in symptoms in 47% of cases, compared with 14% of those given a placebo (a statistically significant difference).² No significant side effects were seen. The amount of aloe used was 100 ml (approximately 3.5 ounces) twice a day for four weeks. Other traditional anti-inflammatory and soothing herbs, including calendula, flaxseed, licorice, marshmallow, myrrh, and yarrow. Many of these herbs are most effective, according to clinical experience, if taken internally as well as in enema form.³ Enemas should be avoided during acute flare-ups but are useful for mild and chronic inflammation. It is best to consult with a doctor experienced with botanical medicine to learn more about herbal enemas before using them. More research needs to be done to determine the effectiveness of these herbs.

In a preliminary trial, people with UC significantly improved on a sugar-free, low-allergen diet with additional nutritional supplementation that included a multivitamin-mineral supplement (2–6 tablets per day); a fish oil supplement (400 mg per day); borage oil (400 mg per day); flaxseed oil (400 mg per day); and a probiotic formula containing Lactobacillus acidophilus and other species of beneficial bacteria.⁴ Some participants received slight variations of this regimen. Since so many different supplements were given and since the trial was not controlled, it is not possible to say which, if any, of the nutrients was responsible for the improvement observed by the researchers.

In a preliminary trial, supplementation with crushed flaxseeds for six weeks improved the average hot flash score (a measure of the frequency and severity of hot flashes) by 57% in postmenopausal women who were not receiving estrogen therapy. The treatment consisted of 2 tablespoons of flaxseeds (along with at least 10 ounces of liquid) twice a day. About one-fifth of the women discontinued treatment because of abdominal symptoms or other side effects.⁵ In a double-blind trial, daily consumption of 25 g of partially defatted ground flaxseed significantly decreased the number of hot flashes and improved overall menopausal symptoms. However, the improvements were not greater than those in women given a placebo (wheat bran).⁶ Because of these conflicting results, the effectiveness of flaxseed as a treatment for menopause remains uncertain.
