The bottom line No known interaction

We found no known interaction between Globemallow and Labetalol 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.

Globemallow and Labetalol

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 Labetalol and Globemallow 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 Globemallow at all — not against Labetalol, 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 Labetalol’s Own FDA Label Lists

This is not an interaction — none of it involves Globemallow. These are the most notable effects listed in the ADVERSE REACTIONS section of Labetalol’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Tiredness
  • Dizziness
  • Vomiting
  • Headache
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Labetalol. Read the label on DailyMed › Globemallow’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Globemallow side to compare — that is a limit of the record, not a statement that Globemallow has no side effects.

From our pharmacist’s overview on the Labetalol page

“Labetalol blocks both alpha and beta receptors to lower blood pressure, and it is often the first choice in pregnancy, so the 176 supplement and herbal interactions on file call for genuine care, starting with the eight rated major. Most of the list pushes on blood pressure itself: over a hundred ingredients either add to labetalol's e…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Globemallow 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 Globemallow reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Globemallow and Labetalol 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 Globemallow

What is Globemallow?

  • Soothing skin irritation
  • Cough and sore throat
  • Digestive upset
  • Minor wounds and inflammation
  • Mouth and throat soothing

Globemallow refers to plants in the genus Sphaeralcea, which have a long history of traditional use among Indigenous peoples of the Americas, mainly as a soothing remedy for skin, throat, and digestive complaints. There is very little modern scientific research on its safety or effectiveness, so its benefits remain unproven. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Sphaeralcea · Malvaceae · Leaves, flowers, roots, and whole aerial parts · Tea, poultice, dried herb, infusion

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