Drug & supplement interaction

Chrysanthemum + Lamotrigine

Lamotrigine brand name: Lamictal.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Chrysanthemum and Lamotrigine 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.

Chrysanthemum and Lamotrigine

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 Lamotrigine and Chrysanthemum 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 Chrysanthemum at all — not against Lamotrigine, 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.

Chrysanthemum safety at a glance

Chrysanthemum overall Use caution Generally well tolerated as a tea, but it can cause allergic reactions in sensitive people.
Pregnancy Avoid Safety during pregnancy has not been established, so it is best avoided unless your doctor approves.
Breastfeeding Avoid There is not enough reliable information on safety while breastfeeding, so caution or avoidance is wise.

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

What to actually watch for

No Interaction Found — But Data Suggests Chrysanthemum and Lamotrigine 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. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Chrysanthemum

    “Topically and via occupational exposure, chrysanthemum can cause allergic reactions. Chrysanthemum allergy symptoms can include urticaria, contact dermatitis, eczema, actinic reticuloid photosensitivity dermatitis, pollinosis, rhinoconjunctivitis, and asthma. There are numerous case reports and studies showing that allergies to Chrysanthemum are very common, with an estimated 60% of Europeans being allergic.”

From our pharmacist’s overview on the Lamotrigine page

“Alcohol, ordinary beer or wine, sits at the top of the interaction list for lamotrigine (Lamictal), with well-documented added sedation, and it sets the tone for a list I would treat with real care. Of the 116 supplements and herbs on file, 78 have sedative effects of their own, so the biggest theme by far is stacked drowsiness and slo…”

About Chrysanthemum

What is Chrysanthemum?

  • Eye irritation and tired eyes
  • Cooling and 'heat-clearing' in traditional Chinese medicine
  • Cold and flu symptoms
  • Headache
  • Soothing/relaxation
  • High blood pressure (traditional use)

Chrysanthemum flowers are most often used as a soothing tea in traditional Chinese medicine and as a folk remedy for eye irritation, colds, and minor inflammation. Solid human evidence for these uses is limited, so it should be seen as a pleasant traditional drink rather than a proven treatment. People allergic to ragweed and related plants, and those who are pregnant or breastfeeding, should be cautious and talk to a pharmacist or doctor first.

Chrysanthemum morifolium · Asteraceae · Flowers (dried flower heads) · Tea, dried flowers, capsules, extracts, topical preparations

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

Chrysanthemum: dosing

There is no official standardized dose for chrysanthemum. It is most often used as a tea made from dried flowers, and supplement strength varies widely between products.If you choose to use it, follow the directions on the product label and start with a small amount to see how you react.

About Lamotrigine

What Is Lamotrigine Used For?

Brand name: Lamictal

Lamotrigine is used to treat several types of seizures in adults and children aged 2 and older — including partial-onset seizures, generalized tonic-clonic (grand mal) seizures, and seizures related to Lennox-Gastaut syndrome. In older teens and adults, it can also be used alone (monotherapy) after transitioning off another seizure medicine.

For adults with bipolar I disorder, lamotrigine is used as a maintenance treatment — meaning it helps delay the return of mood episodes like depression, mania, or mixed states. It is not approved to treat an active manic or mixed episode that's happening right now.

Taking Chrysanthemum and Lamotrigine Together: Common Questions

Is it safe to take Chrysanthemum with Lamotrigine?
We do not list a known interaction between Chrysanthemum and Lamotrigine. 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 Chrysanthemum and Lamotrigine have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Lamotrigine interact with any supplements?
Yes. Lamotrigine has documented interactions with 116 supplements in our database — Chrysanthemum is not one of them. The Lamotrigine interaction page linked on this page lists every one, ranked by severity.
