Botanical Treatments for Hemorrhoids Abascal K, Yarnell E. Botanical treatments for hemorrhoids. Altern Complement Med. 2005;11(6):285-289. Almost one-half of all Americans have some discomfort from hemorrhoids by the time they reach age 50, but only 4% seek medical treatment.1 The authors discuss the roles of butcher's broom (Ruscus aculeatus), horse chestnut (Aesculus hippocastanum), stoneroot (Collinsonia canadensis), witch hazel (Hamamelis virginiana), arnica (Arnica spp.), oak (Quercus spp.), chamomile (Matricaria recutita), gotu kola (Centella asiatica), calendula (Calendula officinalis), and psyllium (Plantago ovata seed) in the treatment of hemorrhoids. Hemorrhoidal tissues, cushions of tissue within the anal canal that contain blood vessels and supporting tissue made up of muscle and elastic tissue, are present in all individuals.2 Hemorrhoids occur when these cushions enlarge and cause negative symptoms, e.g., the passage of bright red blood. Two types of hemorrhoids can occur: internal hemorrhoids, which originate at the top of the anal canal, and external hemorrhoids, which originate at the lower end of the canal, near the anus. According to the authors, botanical treatments for hemorrhoids have been poorly researched. Butcher's broom has a long history of clinical use as a treatment for hemorrhoids, and its use for treating this condition has been approved by the German Commission E.3 The authors cite an open-label multicenter study of 124 patients, in which 69% of those patients rated butcher's broom as having good or excellent efficacy. After taking 6 capsules per day of a product containing 150 mg of butcher's broom for 3 days and then reducing their dose to 4 capsules per day, the patients reported symptom (pain, local signs, overall severity) improvement. Horse chestnut contains a mixture of triterpene saponins (referred to as escins), flavonoids, and tannins. The German Commission E has approved the use of a standardized horse chestnut extract (containing 16%-20% anhydrous escin) for treating chronic venous insufficiency. Although European publications from the late 1800s and early 1900s report that horse chestnut benefits patients who have hemorrhoids, there are no recent studies on its use as a hemorrhoid treatment. The authors cite a double-blinded placebo-controlled study of 80 patients suffering from acute symptomatic hemorrhoids. In 81% of those patients, symptoms were reduced, and bleeding and swelling were notably reduced. In that study, 40 mg of escin was administered 3 times daily for up to 2 months. Stoneroot is used by many American herbalists, including the authors, as a treatment for symptomatic hemorrhoids. The only research on stoneroot is constituent studies showing that it contains flavonoids and saponins. Witch hazel has long been used to treat hemorrhoids. Both European and American herbalists use witch hazel both as an internal and topical remedy. It is prescribed as a decoction or as an alcohol-preserved decoction. In pharmacological studies, it has produced anti-inflammatory, astringent, and vasoconstrictive properties.4 Topical treatments can calm the inflammation and stop the bleeding and swelling associated with hemorrhoids. Rudolf Fritz Weiss, MD (a German phytotherapist) recommended using 1-2 teaspoons of arnica tincture per half-liter water as a wet compress. Alternatively, he recommended the use of an oak bark decoction or a chamomile infusion, and the use of a witch hazel ointment following the application of compresses. The authors recommend combining several herbs in compresses, sitz baths, or ointments to provide a broader range of actions. For topical application, they suggest including herbs noted for their wound-healing properties (e.g., gotu kola, chamomile, or calendula), as well as those used internally (stoneroot, butcher's broom, horse chestnut, and witch hazel). The authors note the importance of other issues in the treatment of hemorrhoids. They recommend an increased intake of fruits and vegetables, as well as increased water intake and exercise, for a long-term reduction of hemorrhoid symptoms. For those patients who are constipated, the authors recommend psyllium seed husks. "A comprehensive treatment plan will work effectively on hemorrhoids in the early stages. More complicated and advanced hemorrhoids are likely to require allopathic intervention. Nonetheless, botanicals as an adjunct to ligation and surgery will be helpful for healing and preventing recurrences," conclude the authors.

Herbal Medicine: The Expanded Commission E Monographs. Newton, Mass: Integrative Medicine Communications; 2000. Prévenir les hémorroïdes Les hémorroïdes sont le plus souvent provoquées par la constipation. La constipation, elle, est en général causée par un mauvais régime alimentaire, le manque d'exercice physique, le stress, et la déshydratation. Elle peut aussi être causée par l'abus de laxatifs chimiques, le syndrome du côlon irritable, et l'hypothyroïdie. Pour prévenir la constipation :
Remèdes naturels contre les hémorroïdes La première plante à utiliser est indiscutablement l'hamamélis. Les Amérindiens l'utilisaient avant Christophe Colomb. La Commission E en Allemagne (sur les plantes médicinales), l'ESCOP et l'Organisation Mondiale de la Santé (OMS) reconnaissent toutes l'usage de l'hamamélis pour soigner les varices et les hémorroïdes. Les feuilles et l'écorce de l'hamamélis renferment de 8 % à 12 % de tanins auxquelles sont attribués les effets astringents, anti-inflammatoires et hémostatiques de la plante. « Astringent » veut dire que les pores de la peau se resserrent sous son effet. La peau se raffermit. Pour renforcer les veines, le fragon faux houx (Ruscus aculeatus) est votre plante de choix. Surnommée la « plante des jambes légères », elle contient un glycoside stéroïdien, la ruscogénine, utilisé dans des pommades pour les hémorroïdes (Ruscorectal) ou les poches sous les yeux. En effet, sa racine, ou plus exactement son rhizome, a des vertus diurétique et vasoconstricteur, ce qui signifie qu'elle resserre les veines. A noter que la ruscogénine est souvent utilisée en association avec la quercétine. C'est un flavonoïde aux effets anti-inflammatoires qui est souvent associé à la vitamine C, et c'est à elle que le ginkgo et le millepertuis doivent leurs vertus médicinales. Prendre 200 à 400 mg trois fois par jour. Le marron d'Inde (Aesculus hippocastanum) renferme lui aussi des tanins catéchiques, des flavonoïdes, des dérivés puriques et des saponosides triterpéniques. |
