Manaca and Tolazamide

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Tolazamide and Manaca in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Manaca at all — not against Tolazamide, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Tolazamide page

“Tolazamide (Tolinase) lowers blood sugar in type 2 diabetes, and I would handle its supplement list with care, because nearly everything listed can drag blood sugar lower still. Herbs and foods with glucose-lowering effects dominate the file, and stacked on a pill that already lowers glucose they raise the odds of hypoglycemia, blood s…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Manaca is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Manaca reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Manaca and Tolazamide records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Manaca

What is Manaca?

  • Joint pain and arthritis
  • Rheumatism
  • Skin conditions
  • As a diuretic
  • Inflammation

Manaca (Brunfelsia uniflora) is a South American shrub traditionally used for arthritis, rheumatism, and skin problems. There is very little reliable human research to support these uses, and the plant belongs to the nightshade family and may be toxic, so caution is strongly advised. Talk to a pharmacist or doctor before using it.

Brunfelsia uniflora · Solanaceae · Roots and bark; sometimes leaves · Tincture, dried root, capsules, tea, homeopathic preparations

An interaction check asks whether these two react with each other — it does not ask whether Manaca is a good idea for someone in your situation. Here is what our Manaca record says about it on its own.

Manaca: dosing

There is no established or standardized dose for manaca. Because the plant may be toxic and has not been tested in proper human studies, safe dosing has not been determined.If you choose to use a product that contains manaca, follow the directions on the label and do not exceed them.

From our Manaca monograph — the full record covers uses, side effects and every documented interaction.

About Tolazamide

What Is Tolazamide Used For?

Brand name: Tolinase

  • Tolazamide is used along with diet and exercise, and sometimes with other medications, to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Tolazamide is in a class of medications called sulfonylureas. Tolazamide lowers blood sugar by causing the pancreas to produce insulin (a natural substance that is needed to break down sugar in the body) and helping the body use insulin efficiently. This medication will only help lower blood sugar in people whose bodies produce insulin naturally. Tolazamide is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may occur if high blood sugar is not treated).

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
