Lavender Cotton + Zileuton
Zileuton brand names: Zyflo, Zyflo CR.
We found no known interaction between Lavender Cotton and Zileuton 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 Zileuton states a food rule worth keeping to.
Lavender Cotton and Zileuton
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 Zileuton and Lavender Cotton 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 Lavender Cotton at all — not against Zileuton, 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.
Lavender Cotton safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Zileuton Products Have a Food Rule — Lavender Cotton Should Not Break It
At least one FDA label for a product containing Zileuton says to take it with food. If you take Lavender Cotton on an empty stomach out of habit, keep them separate — and take Zileuton 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 Zileuton 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.
For ease of administration, ZYFLO may be taken with meals and at bedtime.

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.

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Lavender Cotton 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 Lavender Cotton reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Lavender Cotton and Zileuton 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 Lavender Cotton
What is Lavender Cotton?
- Digestive upset
- Intestinal worms (traditional)
- Insect repellent
- Minor skin irritation
- Menstrual discomfort (traditional)
Lavender cotton (Santolina chamaecyparissus) is a fragrant Mediterranean shrub used in folk medicine for digestion, worms, and as an insect repellent, but there is very little modern human research to support any of these uses. Because reliable safety and effectiveness data are lacking, it is best used cautiously and avoided in pregnancy and breastfeeding. Talk to your pharmacist or doctor before trying it.
Santolina chamaecyparissus · Asteraceae · Flowering tops, leaves, and essential oil · Dried herb, tea/infusion, essential oil, topical preparations
An interaction check asks whether these two react with each other — it does not ask whether Lavender Cotton is a good idea for someone in your situation. Here is what our Lavender Cotton record says about it on its own.
Lavender Cotton: dosing
There is no established or standardized dose for lavender cotton. Traditional use as a mild tea does not mean a safe dose has been scientifically defined, and the essential oil is much more concentrated than the dried herb.If you choose to use a product, follow the directions on the label and do not exceed them. Essential oils should be kept out of reach of children and never taken by mouth without professional guidance.

About Zileuton
What Is Zileuton Used For?
Brand names: Zyflo, Zyflo CR
Zileuton is used for the ongoing prevention and treatment of asthma in adults and adolescents aged 12 and older. It is a maintenance medicine — meaning it is taken regularly to keep asthma under control, not to stop an asthma attack once it has started.
Zyflo (the tablet form) and zileuton extended-release tablets are both approved for this same purpose. Neither form should be used to treat a sudden asthma attack. However, both can be continued during a flare-up of asthma while you also use your rescue inhaler.
