Interaction report

Guarumo and Collagenase Clostridium Histolyticum-Aaes

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 Collagenase Clostridium Histolyticum-Aaes and Guarumo 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.

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.

Guarumo overall Use caution It has a long history of traditional use, but human safety data are very limited.

What to actually watch for

What Guarumo Itself Has Been Linked To

This is not an interaction — nothing below involves Collagenase Clostridium Histolyticum-Aaes. It is the side-effect record for Guarumo on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Guarumo, this list is the first place to look.

Heartburn Additional detail
“Orally, guarumo seems to be well tolerated when used as a tea. Rare side effects reported in a clinical trial include excessive salivation, heartburn, and exhaustion. Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.”

“Orally, excessive salivation and heartburn were reported by one patient each after drinking tea prepared from 1 gram of dried guarumo leaves three times daily before meals for 21 days.”

Everything above comes from the Natural Medicines adverse-effect record for Guarumo — expand a row for the licensed statement it rests on. We haven’t matched Collagenase Clostridium Histolyticum-Aaes to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Collagenase Clostridium Histolyticum-Aaes.

About Guarumo

What is Guarumo?

Type 2 diabetes / blood sugar support
High blood pressure
Cough, asthma, and bronchitis
Heart failure symptoms
Liver and rheumatic complaints

Guarumo (Cecropia obtusifolia) is a tropical tree used in Latin American traditional medicine, most often as a leaf tea for diabetes and high blood pressure. Some early laboratory and small human studies suggest it may modestly affect blood sugar, but the evidence is limited and not strong enough to recommend it as a treatment. Talk with your pharmacist or doctor before using it, especially if you have a chronic condition or take medication.

Cecropia obtusifolia · Urticaceae · Leaves (most common), bark, and root · Tea (infusion or decoction), liquid extracts, capsules, and dried leaf

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

Guarumo: dosing

There is no established standard dose for guarumo. Traditional use most often involves a tea made from the dried leaves, but the amount of active compounds can vary a lot between products and even between batches.If you choose to use a guarumo product, follow the directions on the label and do not exceed them.

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

About Collagenase Clostridium histolyticum Injection

What Is Collagenase Clostridium histolyticum Injection Used For?

Brand name: Qwo

Collagenase Clostridium histolyticum injection (Xiaflex) is used to treat Dupuytren's contracture (a painless thickening and tightening of tissue [cord] beneath the skin in the palm of the hand, which may make it difficult to straighten one or more fingers) when a cord of tissue can be felt upon examination. Collagenase Clostridium histolyticum injection (Xiaflex) is also used to treat Peyronie's disease (a thickening of tissue [plaque] inside the penis that causes the penis to curve). Collagenase Clostridium histolyticum injection (QWO) is also used to treat cellulite (fat deposit beneath the skin) in the buttocks of adult women. Collagenase Clostridium histolyticum injection is in a class of medications called enzymes. In people with Dupuytren's contracture, it works by helping to break down the cord of thickened tissue and allows the finger(s) to be straightened. In people with Peyronie's disease, it works by helping to break down the plaque of thickened tissue and allows the penis to be straightened. In women with cellulite, it works by releasing fibrous bands, redistributing fat cells, and stimulating the growth of new collagen.
