Smartweed and Enalapril Maleate

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 Enalapril Maleate and Smartweed 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.

Smartweed safety at a glance

Smartweed overall Use caution There is little modern safety data, so use cautiously and talk to a healthcare provider first.
Pregnancy Avoid Traditionally used to affect menstruation and the uterus, so avoid during pregnancy.
Breastfeeding Avoid There is not enough safety information, so it is best to avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Enalapril Maleate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Enalapril Maleate is filed under 5 classifications — including ace inhibitors (aceis), antihypertensive drugs, photosensitizing drugs. Smartweed has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Enalapril Maleate’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.

What to actually watch for

What Enalapril Maleate’s Own FDA Label Lists

This is not an interaction — none of it involves Smartweed. These are the most notable effects listed in the ADVERSE REACTIONS section of Enalapril Maleate’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. 2 of them are worth acting on rather than waiting out — marked below.

  • Heart failure Worth acting on
  • Raised blood pressure Worth acting on
  • Tiredness

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

From our pharmacist’s overview on the Enalapril Maleate page

“Potassium is the supplement I worry about first with enalapril maleate (Vasotec, Epaned). This ACE inhibitor, used for high blood pressure and heart failure, already makes the body hold onto potassium, so adding more can raise blood levels too far, a problem called hyperkalemia.”

About Smartweed

What is Smartweed?

Smartweed
  • Digestive upset
  • Minor skin irritation
  • Heavy menstrual bleeding (traditional)
  • Wound and bleeding (traditional topical use)
  • Antioxidant and anti-inflammatory support

Smartweed (Persicaria hydropiper) is a peppery wetland plant with a long history in traditional medicine for digestive complaints, bleeding, and skin problems. Modern human studies are very limited, so its benefits are not well proven. Because safety data are thin, it's best to use cautiously and avoid it during pregnancy and breastfeeding.

Persicaria hydropiper · Polygonaceae · Aerial parts (leaves, stems, and flowering tops); sometimes the whole plant · Tea, tincture, liquid extract, dried herb, and topical preparations

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

Smartweed: dosing

There is no well-established or standardized dose for smartweed. Because it has not been carefully studied in people, experts cannot recommend a safe and effective amount.If you choose to use a product, follow the directions on the label and do not exceed them.

About Enalapril

What Is Enalapril Used For?

Brand names: Vasotec, Epaned

Enalapril is used to treat high blood pressure (hypertension) in adults and children older than one month, and to treat symptomatic heart failure. Lowering blood pressure reduces the risk of stroke and heart attack.

It is also used for asymptomatic left ventricular dysfunction — when the heart's pumping ability is reduced but the person doesn't yet have obvious heart failure symptoms — to slow the progression to overt heart failure and reduce hospitalizations. Enalapril maleate oral solution (including Epaned) and enalapril maleate tablets (including Vasotec) share these three approved uses.
