Drug & supplement interaction

Tree Of Heaven + Ranolazine

Ranolazine brand names: Ranexa, Aspruzyo.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Tree Of Heaven and Ranolazine 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Tree Of Heaven and Ranolazine

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 Ranolazine and Tree Of Heaven 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.

Tree Of Heaven safety at a glance

Tree Of Heaven overall Use caution Human safety data are limited, and the plant can irritate the stomach and skin.
Pregnancy Avoid Not enough safety information; traditional use for menstrual effects raises concern, so avoid in pregnancy.
Breastfeeding Avoid No reliable safety data during breastfeeding, so it is best avoided.

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

How we checked

Why No Interaction Is Listed for Ranolazine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ranolazine is filed under 5 classifications — including cytochrome p450 2d6 (cyp2d6) inhibitors, qt interval-prolonging drugs, p-glycoprotein substrates. Tree Of Heaven has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Ranolazine’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.

No Interaction Found — But Data Suggests Tree Of Heaven and Ranolazine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

About Tree Of Heaven

What is Tree Of Heaven?

  • Diarrhea and dysentery
  • Intestinal parasites
  • Menstrual or vaginal complaints
  • Asthma and cough (traditional use)
  • Skin conditions (topical, traditional use)

Tree of Heaven (Ailanthus altissima) is a fast-growing, invasive tree whose bark has been used in traditional medicine, mostly for digestive complaints and parasites. Modern scientific evidence in humans is very limited, and the plant can cause stomach upset and skin reactions, so it should be used cautiously and not without professional guidance.

Ailanthus altissima · Simaroubaceae · Bark (especially root and stem bark), leaves · Dried bark, tinctures, teas/decoctions, traditional herbal preparations

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

Tree Of Heaven: dosing

There is no well-established or standardized dose for Tree of Heaven. Traditional preparations such as bark decoctions varied widely, and they were not measured against modern safety standards.If you choose to use a commercial product, follow the directions on the label and do not exceed them.
