Butcher's Broom Side Effects and Blood Pressure
Butcher's broom side effects are mainly diarrhea and, with creams, skin reactions. Our main source does not discuss blood pressure, so no safe or unsafe claim can be made there. Memorial Sloan Kettering advises people with diabetes against it. In the Synaptril blend, butcher's broom root extract is listed third.

The short answer01
What are butcher's broom side effects?
Butcher's broom side effects are mostly diarrhea. Skin reactions have been reported after use on the skin.
Memorial Sloan Kettering says small studies of products containing butcher's broom suggest help with chronic venous insufficiency, a vein problem in the legs. Long-term safety and effectiveness are unknown (MSKCC, Butcher's broom).
The diarrhea reports came mainly with one combination product, so it is hard to say how much is the herb itself (MSKCC, Butcher's broom).
The same source finds a lack of evidence for hemorrhoids, constipation, leg cramps and urine flow. It does not discuss memory or any thinking use.
Blood pressure02
Does butcher's broom affect blood pressure?
We cannot say. None of the sources we use gives a reliable answer on butcher's broom and blood pressure.
MSKCC's page lists no drug interactions and does not address blood pressure drugs (MSKCC, Butcher's broom). A missing warning is not a safe sign. It means the question is open.
| Question | Answer |
|---|---|
| Raises or lowers blood pressure? | Not covered by our sources |
| Interacts with medicines? | None listed; not studied |
| Helps veins? | Small studies of combination products (MSKCC, Butcher's broom) |
| Helps memory? | Not discussed; no brain studies found |
| Safe long term? | Unknown (MSKCC, Butcher's broom) |
Keep taking it. Ask your doctor or pharmacist before adding any new herb, and tell them the full ingredient list.
Who should skip it03
Who should not take butcher's broom?
People with diabetes should not use butcher's broom, says Memorial Sloan Kettering. It cites a 39-year-old woman who developed diabetic ketoacidosis five days after using it (MSKCC, Butcher's broom).
That is one case, and the cause is not proven. It is still enough for the cancer center to advise against use.
Synaptril's label also says it is not for people under 18 or pregnant or nursing mothers, and that anyone on a medication or with a condition should consult a physician first. Read the full side effects page for the other five ingredients.

How much butcher's broom is in Synaptril?
The label does not say. Butcher's broom is third in the 575 mg blend, so it holds at most 192 mg per capsule.
That ceiling is 575 divided by 3. The real amount is lower, because pure magnesium glycinate alone likely takes about 570 mg. In a generous case, where it takes 400 mg, butcher's broom gets at most 88 mg.
No vein study we found used a Synaptril-like dose or form. See the butcher's broom page. Keep taking any prescribed medicine, and do not change it because of a supplement.
FAQ05
Butcher's broom side effect questions
Can butcher's broom cause diarrhea?
Yes. Diarrhea is the main side effect reported, mostly with one combination product (MSKCC, Butcher's broom). If loose stools start after a new supplement, stop it and ask your pharmacist. Several Synaptril blend ingredients can do the same.
Is butcher's broom safe for people with diabetes?
MSKCC advises against it for people with diabetes after a case of ketoacidosis in a 39-year-old woman (MSKCC, Butcher's broom). If you have diabetes, ask your doctor before using any product that contains it.
Does butcher's broom thin the blood?
Our sources do not say. The MSKCC page lists no drug interactions (MSKCC, Butcher's broom), which means none are documented there, not that none exist. If you take a blood thinner, ask your doctor about every ingredient.
Is butcher's broom used for brain health?
It is traditionally used for veins. MSKCC does not discuss memory or focus for it, and we found no brain studies (MSKCC, Butcher's broom). Its place in a brain formula rests on the maker's reasoning, not trial results.
What does the Ruscus aculeatus root extract on the label mean?
Ruscus aculeatus is the Latin name for butcher's broom. The label lists its root extract as the third ingredient of the blend. No extract ratio or amount is printed, so the strength cannot be judged.
How long has butcher's broom been studied for safety?
Only in short studies. MSKCC states long-term safety and effectiveness are unknown (MSKCC, Butcher's broom). Synaptril's directions call for one capsule daily with no stated end date, so check in with your doctor at 30 and 60 days.
