Laurelwood + Fingolimod

Fingolimod brand names: Gilenya, Tascenso ODT.

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 Laurelwood and Fingolimod 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.

Laurelwood and Fingolimod

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 Fingolimod and Laurelwood 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 Laurelwood at all — not against Fingolimod, 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.

No Interaction Found — But Data Suggests Laurelwood and Fingolimod May Share a Side Effect

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.

Orally, calanolide A, a constituent of laurelwood, has been reported to cause an oily aftertaste, nausea, dizziness, and headache.

From our pharmacist’s overview on the Fingolimod page

“Fingolimod (Gilenya, Tascenso ODT) reins in the immune system to keep multiple sclerosis quiet, and its supplement file calls for genuine wariness. Half of the entries are herbs and extracts thought to stimulate immunity, which could blunt the drug's whole purpose.”

About Laurelwood

What is Laurelwood?

  • Skin care and moisturizing
  • Minor wounds and scars
  • Acne-prone skin
  • Dry or irritated skin
  • Soothing minor burns or insect bites

Laurelwood, the source of tamanu oil, is a tropical tree whose seed oil is used mainly on the skin for moisturizing, soothing irritation, and supporting wound healing. Most evidence is preliminary or based on laboratory studies, and it is meant for external use only. Talk to a pharmacist or doctor before using it, and avoid swallowing the oil.

Calophyllum inophyllum · Calophyllaceae · Seeds (pressed into oil), and at times the bark and leaves · Tamanu oil (cold-pressed seed oil), creams, balms, and topical skincare products

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

Laurelwood: dosing

There is no official or standardized dose for laurelwood (tamanu) oil. It is used topically, and the amount depends on the product and the area being treated.The safest approach is to follow the directions on the product label and to start with a small amount on a small area.

About Fingolimod

What Is Fingolimod Used For?

Brand names: Gilenya, Tascenso ODT

Fingolimod — available as capsules (Fingolimod, Fingolimod Hydrochloride, and Gilenya) and as an orally disintegrating tablet (Tascenso ODT) — is approved for the treatment of relapsing forms of multiple sclerosis (MS) in patients 10 years of age and older. This includes clinically isolated syndrome (a first MS episode), relapsing-remitting MS (the most common type with flare-ups and periods of stability), and active secondary progressive MS (a later stage where disability gradually worsens but relapses still occur).

All supported formulations share these same approved uses. The goal of treatment is to reduce the frequency of relapses and slow disease activity.

Taking Laurelwood and Fingolimod Together: Common Questions

Is it safe to take Laurelwood with Fingolimod?
We do not list a known interaction between Laurelwood and Fingolimod. 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 Laurelwood and Fingolimod have any of the same side effects?
Yes — our sources link each of them separately to one 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 Fingolimod interact with any supplements?
Yes. Fingolimod has documented interactions with 106 supplements in our database — Laurelwood is not one of them. The Fingolimod interaction page linked on this page lists every one, ranked by severity.
