Butcher's broom

Two meta-analyses of placebo-controlled trials found Ruscus products, mostly combined with hesperidin methyl chalcone and vitamin C, reduced leg pain and heaviness in chronic venous disease. One found smaller ankle circumference and leg volume, while the other found no significant change in circumference. Case reports describe chronic diarrhea with colitis and one case of diabetic ketoacidosis.

Leg pain, heaviness and other venous symptoms

Shown to reduce leg pain, heaviness, tingling and fatigue in adults with chronic venous disease, across 10 placebo-controlled trials.

The numbers and sources
Effect
In 10 placebo-controlled trials (719 patients), Ruscus reduced leg pain (RR 0.35), heaviness (RR 0.26), feeling of swelling (RR 0.53) and tingling (RR 0.27). As continuous measures, pain (SMD -0.80, 95% CI -1.21 to -0.39), heaviness (SMD -1.23, 95% CI -1.60 to -0.86) and fatigue (SMD -1.16) fell [1]. An earlier meta-analysis of Cyclo 3 Fort, with data from 10,246 people across 20 placebo-controlled and other studies, found that on a 0 to 3 severity scale pain fell by 0.44 points, heaviness by 0.53, tingling by 0.29 and cramps by 0.26 more than on placebo [2].
Population
Adults with chronic venous disease or insufficiency [1][2].
Sources
[1], [2]
Caveats
The feeling of swelling result had considerable heterogeneity [1]. The earlier analysis also drew on single-arm and comparator studies, and its authors note variable data quality and sample size [2].
Moderate

Leg swelling

Shown to reduce ankle circumference and leg volume in adults with chronic venous disease, mostly for Ruscus combined with hesperidin methyl chalcone and vitamin C. One meta-analysis disagreed.

The numbers and sources
Effect
In placebo-controlled trials, Ruscus reduced ankle circumference (SMD -0.74, 95% CI -1.01 to -0.47) and leg or foot volume (SMD -0.61, 95% CI -0.91 to -0.31) [1]. In the Cyclo 3 Fort meta-analysis, edema severity (0.43 points), calf circumference (0.73 cm) and ankle circumference (1.17 cm) fell more than on placebo, but none of these differences was statistically significant [2]. In 148 women given a Ruscus-only extract for 12 weeks, leg volume fell 16.5 mL more than placebo at 8 weeks and 20.5 mL more at 12 weeks, with smaller ankle and leg circumference [3].
Population
Adults with chronic venous disease [1][2]. 166 women with chronic venous insufficiency, 148 analyzed [3].
Sources
[1], [2], [3]
Caveats
The two meta-analyses disagree on circumference [1][2]. Most trials tested Ruscus combined with hesperidin methyl chalcone and vitamin C [1][2].

Claimed, not studied in people1

Untested

Hemorrhoids

Not studied in people. The EU herbal committee accepts butcher's broom root for itching and burning of hemorrhoids on the basis of at least 30 years of use.

No study in people. This rests on documented traditional use.

The numbers and sources
Effect
The European Medicines Agency's herbal committee concluded that, on the basis of long-standing use, butcher's broom root preparations can be used to relieve itching and burning of hemorrhoids after a doctor has ruled out serious conditions. It states that no studies in patients with hemorrhoids have been carried out with butcher's broom, and that traditional use means the effect is plausible and there is a record of use this way for at least 30 years, 15 of them in the EU [6].
Population
A regulator's review of traditional use in the EU [6].
Sources
[6]
Caveats
Traditional use is a record of how long it has been used, not a test of its effect [6]. Old French and German reports on Ruscus in proctology were located but have no abstracts to read.

Doses studied

Cyclo 3 Fort capsules contain 150 mg Ruscus root extract, 150 mg hesperidin methyl chalcone and 100 mg ascorbic acid [2]. The Ruscus-only trial used the daily dose set by the German monograph for 12 weeks. The abstract does not state the amount [3].

Risks

Reported risks2

Limited

Chronic diarrhea and lymphocytic colitis

Case reports: three people developed lymphocytic colitis with chronic diarrhea during long-term use of a Ruscus combination product.

The numbers and sources
Effect
Three people developed lymphocytic colitis with chronic diarrhea during long-term use of Cyclo 3 Fort. In one, signs of immune activation in the bowel lining returned when the drug was restarted [4].
Population
Three case reports [4].
Sources
[4]
Caveats
Case reports cannot give a rate. The product combines Ruscus with hesperidin methyl chalcone and vitamin C, so the component involved is not known [4].
Limited

Diabetic ketoacidosis

Case reports: a woman with diabetes developed diabetic ketoacidosis 5 days after starting butcher's broom, and recovered with treatment.

The numbers and sources
Effect
A 39-year-old woman with diabetes developed diabetic ketoacidosis, with a blood pH of 7.02 and high potassium, 5 days after starting butcher's broom for mild ankle swelling. She recovered with fluids, insulin and calcium gluconate [5].
Population
One case report [5].
Sources
[5]
Caveats
A single case.

Adverse events in trials

One 12-week trial recorded 22 of 48 adverse events on Ruscus, with one judged unlikely to be related.

The numbers and sources
Effect
In the 12-week Ruscus-only trial, 48 adverse events occurred across both groups, 22 of them on Ruscus. One was judged related to the study medication, and that link was rated unlikely [3].
Population
148 women with chronic venous insufficiency [3].
Sources
[3]
Caveats
One trial lasting 12 weeks.
