Drug & supplement interaction

Tree Tobacco + Aldesleukin

Aldesleukin brand name: Proleukin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Tree Tobacco and Aldesleukin 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 Tobacco and Aldesleukin

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 Aldesleukin and Tree Tobacco 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 Tree Tobacco at all — not against Aldesleukin, 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.

What to actually watch for

No Interaction Found — But Data Suggests Tree Tobacco and Aldesleukin 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Confusion Worth acting on Additional detail

    Tree Tobacco

    “Orally, tree tobacco is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Tree tobacco can cause nausea, vomiting, diarrhea, abdominal pain, changes in blood pressure and heart rate, muscle weakness and paralysis, respiratory distress, and neurological symptoms including vertigo, confusion, fatigue, headache, hallucinations, spasms, weakness, and coma.”

See Every Supplement That Interacts With Aldesleukin

This page covers Tree Tobacco only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aldesleukin page lists 42 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Asarabacca (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Aristolochia (moderate).

By severity: 4 major · 37 moderate · 1 minor.

From our pharmacist’s overview on the Aldesleukin page

“Aldesleukin (Proleukin) is high-dose immunotherapy for advanced kidney cancer and melanoma, and the drug is itself notoriously hard on the liver and kidneys, so this list earns real wariness. All 42 supplement interactions on file land on those same two organs: 38 ingredients can add liver strain and 6 can add kidney strain.”

About Tree Tobacco

What is Tree Tobacco?

  • Topical use on wounds or sores (folk use)
  • Joint and muscle pain (folk use)
  • Headache relief (traditional poultice)
  • Insect or pest control

Tree tobacco is a poisonous shrub that contains the toxic alkaloid anabasine, and it is not a safe dietary supplement. There is no reliable evidence that it treats any condition, and swallowing it can cause severe poisoning or death. We strongly recommend avoiding internal use entirely.

Nicotiana glauca · Solanaceae · Leaves · Crushed leaves, poultices, traditional topical preparations

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

Tree Tobacco: dosing

There is no safe or established dose for tree tobacco. It is not sold or recommended as a standardized dietary supplement, and no amount is known to be safe to swallow.Because of its toxicity, we recommend avoiding it entirely.

Taking Tree Tobacco and Aldesleukin Together: Common Questions

Is it safe to take Tree Tobacco with Aldesleukin?
We do not list a known interaction between Tree Tobacco and Aldesleukin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Tree Tobacco and Aldesleukin have any of the same side effects?
Yes — our sources link each of them separately to 8 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Aldesleukin interact with any supplements?
Yes. Aldesleukin has documented interactions with 42 supplements in our database — Tree Tobacco is not one of them. The Aldesleukin interaction page linked on this page lists every one, ranked by severity.
