The bottom line No known interaction

We found no known interaction between Guarumo and Cyproheptadine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Interaction report

Guarumo and Cyproheptadine

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 Cyproheptadine 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 safety at a glance

Guarumo overall Use caution It has a long history of traditional use, but human safety data are very limited.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Cyproheptadine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cyproheptadine is filed under 4 classifications — including anticholinergic drugs, photosensitizing drugs, seizure threshold lowering drugs. Guarumo has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and cns depressants (moderate) — and none of Cyproheptadine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What to actually watch for

What Guarumo Itself Has Been Linked To

This is not an interaction — nothing below involves Cyproheptadine. 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 read the ADVERSE REACTIONS section of Cyproheptadine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Cyproheptadine column appears here.

See Every Supplement That Interacts With Cyproheptadine

This page covers Guarumo only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cyproheptadine page lists 72 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Henbane (major), Scopolia (major), Alfalfa (moderate) and Angel's Trumpet (moderate).

By severity: 3 major · 57 moderate · 12 minor.

From our pharmacist’s overview on the Cyproheptadine page

“Cyproheptadine (Periactin) is an older antihistamine that dries you out and slows you down on its own, which is exactly why its supplement list warrants genuine care rather than a quick skim. Of the 72 ingredients on file, three carry a major rating.”

About Guarumo

What is Guarumo?

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.

About Cyproheptadine

What Is Cyproheptadine Used For?

Brand name: Periactin

Cyproheptadine treats a range of allergic conditions, including perennial and seasonal allergic rhinitis (year-round or seasonal nasal allergies), vasomotor rhinitis (non-allergic nasal symptoms), and allergic conjunctivitis (itchy, watery eyes caused by allergens or foods). It also helps with allergic skin reactions such as urticaria (hives) and angioedema (skin swelling).

Additional uses include cold urticaria (hives triggered by cold), dermatographism (skin that hives when scratched), and helping to calm allergic reactions to blood or plasma transfusions. It is also used as a supportive therapy alongside epinephrine after a severe allergic reaction (anaphylaxis) has been initially controlled.
