The bottom line No known interaction

We found no known interaction between Lemon Balm and Insulin (rDNA) 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 label for Insulin (rDNA) states a food rule worth keeping to.

Interaction report

Lemon Balm and Insulin (rDNA)

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 Insulin (rDNA) and Lemon Balm 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.

Lemon Balm safety at a glance

Lemon Balm overall Use caution Generally well tolerated for short-term use in most healthy adults, but high doses and long-term safety are not well studied.
Pregnancy Avoid Not enough reliable safety data, so it is best avoided during pregnancy unless your doctor advises otherwise.
Breastfeeding Use caution Limited safety information exists, so use caution and talk to your doctor before using 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 Insulin (rDNA)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Insulin (rDNA) is filed under 2 classifications — including antidiabetes drugs. Lemon Balm has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and thyroid hormone (moderate) — and none of Insulin (rDNA)’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

Lemon Balm Does Interact With Other Medications

Lemon Balm has 264 moderate known drug interactions in our database — Insulin (rDNA) isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

What Lemon Balm Itself Has Been Linked To

This is not an interaction — nothing below involves Insulin (rDNA). It is the side-effect record for Lemon Balm on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Lemon Balm, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • An irregular heartbeat Worth acting on Additional detail

    “Orally, a case of transient complete atrioventricular block and QT prolongation is reported in a 25-year-old female following the post-workout use of a specific product (Muscle Eze Advanced) containing lemon balm and several other ingredients. Symptoms of fatigue and lightheadedness started 1 week into use of the product.”

  • Drowsiness Additional detail

    “Orally, lemon balm has been reported to cause dizziness and sedation; however, it does not seem to occur more often with lemon balm than placebo. Additionally, other clinical research shows that using lemon balm in conjunction with alcohol does not affect reaction time or influence cognitive performance.”

  • Tiredness Additional detail

    Recorded for Lemon Balm in the same Natural Medicines adverse-effect record shown under An irregular heartbeat above.

  • Dizziness Additional detail

    Recorded for Lemon Balm in the same Natural Medicines adverse-effect record shown under Drowsiness above.

Everything above comes from the Natural Medicines adverse-effect record for Lemon Balm — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Insulin (rDNA)’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Insulin (rDNA) column appears here.

How to take them

Some Insulin (rDNA) Products Have a Food Rule — Lemon Balm Should Not Break It

At least one FDA label for a product containing Insulin (rDNA) says to take it with food. If you take Lemon Balm on an empty stomach out of habit, keep them separate — and take Insulin (rDNA) with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Insulin (rDNA) products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.1 , 2.2 , 2.3 , 2.4 ) Subcutaneous injection ( 2.2 ): Administer HUMALOG ® U-100 or U-200 by subcutaneous injection into the abdominal wall, thigh, upper arm, or buttocks within 15 minutes before a meal or immediately after a meal.

From the Dosage and Administration section of the FDA label we read for Insulin (rDNA) — where that label names a specific product, the instruction is that product's. See the Insulin (rDNA) drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Insulin (rDNA)

This page covers Lemon Balm only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Insulin (rDNA) page lists 242 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Chelation Therapy Products (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 211 moderate · 29 minor.

From our pharmacist’s overview on the Insulin (rDNA) page

“A weed called Siberian cocklebur has caused severe low blood sugar in humans and is the one ingredient to avoid outright while using insulin (rDNA) products like Humalog or Humulin. This list deserves real respect.”

About Lemon Balm

What is Lemon Balm?

Lemon Balm
  • Anxiety and stress
  • Sleep problems
  • Digestive upset
  • Cold sores
  • Restlessness or nervousness

Lemon balm is a gentle, lemon-scented mint-family herb traditionally used to ease stress, support sleep, and calm digestion, and topically for cold sores. Early studies are promising but generally small, so the evidence is limited. It is usually well tolerated for most adults, but pregnant or breastfeeding people should check with a doctor or pharmacist first.

Melissa officinalis · Lamiaceae · Leaves and essential oil · Tea, capsules, tablets, liquid extracts, tinctures, topical creams, and essential oil

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

Lemon Balm: dosing

There is no single standard dose of lemon balm that has been firmly established. The right amount can depend on the form (tea, capsule, extract, or cream) and the reason it is being used.Because products vary widely in strength, the best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Lemon Balm and Insulin (rDNA) Together: Common Questions

Is it safe to take Lemon Balm with Insulin (rDNA)?
We do not list a known interaction between Lemon Balm and Insulin (rDNA). 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.
Should I take Lemon Balm and Insulin (rDNA) at the same time of day?
At least one FDA label for a product containing Insulin (rDNA) says to take it with food. If you take Lemon Balm on an empty stomach out of habit, keep them separate and take Insulin (rDNA) with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Insulin (rDNA) products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Lemon Balm and Insulin (rDNA) combination checked?
Interactions in our licensed database are recorded against drug classes. Insulin (rDNA) is filed under 2 classifications, and Lemon Balm has documented interactions with 2 drug classes — none of Insulin (rDNA)'s classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lemon Balm interact with any other medications?
Yes. Lemon Balm has 264 documented drug interactions in our database — Insulin (rDNA) is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Insulin (rDNA) interact with any supplements?
Yes. Insulin (rDNA) has documented interactions with 242 supplements in our database — Lemon Balm is not one of them. The Insulin (rDNA) interaction page linked on this page lists every one, ranked by severity.
