Constipation

Only the dried form of cascara should be used. Capsules providing 20 to 30 mg of cascarosides per day can be used. However, the smallest amount necessary to maintain soft stool should be used.² As a tincture, 1/4 to 1 teaspoon (1–5 ml) per day is generally taken. It is important to drink eight 6-ounce (180 ml) glasses of water throughout the day while using cascara. Cascara should be taken consecutively for no longer than eight to ten days.³

The laxatives most frequently used world-wide come from plants. Herbal laxatives are either bulk-forming or stimulating.

Stimulant laxatives are high in anthraquinone glycosides, which stimulate bowel muscle contraction. The most frequently used stimulant laxatives are senna leaves, cascara bark, and aloe latex. While senna is the most popular, cascara has a somewhat milder action. Aloe is very potent and should be used with caution. Other stimulant laxatives include buckthorn, alder buckthorn (Rhamnus frangula), and rhubarb (Rheum officinale, R. palmatum).

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.⁴

Glucomannan is a water-soluble dietary fiber that is derived from konjac root. Like other sources of fiber, such as psyllium and fenugreek, glucomannan is considered a bulk-forming laxative. A preliminary trial⁵ and several double-blind trials^6,7,8,9 have found glucomannan to be an effective treatment for constipation. The amount of glucomannan shown to be effective as a laxative is 3 to 4 grams per day. In constipated people, glucomannan and other bulk-forming laxatives generally help produce a bowel movement within 12 to 24 hours.

Many doctors recommend taking 7.5 grams of psyllium seeds or 5 grams of psyllium husks, mixed with water or juice, one to two times per day. Some doctors use a combination of senna (18%) and psyllium (82%) for the treatment of chronic constipation. This has been shown to work effectively for people in nursing homes with chronic constipation.¹²

Senna contains hydroxyanthracene glycosides known as sennosides. These glycosides stimulate colon activity and thus have a laxative effect. Also, these glycosides increase fluid secretion by the colon, with the effect of softening the stool and increasing its bulk.¹ Double-blind trials have confirmed the benefit of senna in treating constipation.^13,14Constipation induced by drugs such as the anti-diarrhea medicine loperamide (Imodium) has also been shown to be improved by senna in a clinical trial.¹⁵

Only the dried form of alder buckthorn should be used. Capsules providing 20 to 30 mg of anthraquinone glycosides (calculated as glucofrangulin A) per day can be used; however, the smallest amount necessary to maintain regular bowel movements should be used.¹⁷ As a tincture, 5 ml once at bedtime is generally taken. Alder buckthorn is usually taken at bedtime to induce a bowel movement by morning. It is important to drink eight six-ounce glasses of water throughout the day while taking alder buckthorn, and to consume plenty of fresh fruits and vegetables. Alder buckthorn should be taken for a maximum of eight to ten days consecutively or else it can lead to dependence on it to have a bowel movement.¹⁷ Some people take peppermint tea or capsules with alder buckthorn to prevent griping, an unpleasant sensation of strong contractions in the colon sometimes induced by the herb.

Basil (Ocimum basilicum) seed has been found to relieve constipation by acting as a bulk-forming laxative in one preliminary study.¹⁹ A similar study showed the seeds to be useful following major surgery for elderly people with constipation.²⁰Alginic acid, one of the major constituents in bladderwrack (Fucus vesiculosus), is a type of dietary fiber that may be used to relieve constipation. However, human studies have not been conducted on the effectiveness of bladderwrack for this condition.

Only the dried form of buckthorn berries and bark should be used. Capsules providing 20 to 30 mg of anthraquinone glycosides (calculated as glucofrangulin A) per day can be used; however, the smallest amount necessary to maintain regular bowel movements should be used.²¹ As a tincture, 5 ml once at bedtime is generally taken. Usually buckthorn is taken at bedtime, so it will have time to act and by morning a bowel movement is induced. It is important to drink eight six-ounce glasses of water throughout the day while taking buckthorn, and to consume plenty of fresh fruits and vegetables. Buckthorn should be taken for a maximum of eight to ten days consecutively or else it can lead to dependence on it to have a bowel movement.²¹ Some people take peppermint tea or capsules with buckthorn to prevent griping, an unpleasant sensation of strong contractions in the colon sometimes induced by buckthorn.

Chlorophyll, the substance responsible for the green color in plants, may be useful for a number of gastrointestinal problems. In a preliminary trial, chlorophyll supplementation eased chronic constipation in elderly people.²⁴

The unprocessed roots of fo-ti possess a mild laxative effect. The bitter compounds in dandelion leaves and root are also mild laxatives.
