Lavender Cotton + Anastrozole
Anastrozole brand name: Arimidex.
We found no known interaction between Lavender Cotton and Anastrozole 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.
Lavender Cotton and Anastrozole
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 Anastrozole 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 Anastrozole, 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.

See Every Supplement That Interacts With Anastrozole
This page covers Lavender Cotton only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Anastrozole page lists 22 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), 7-methoxyflavone (moderate), Arimistane (moderate), Atractylodes (moderate) and Chrysin (moderate).
By severity: 1 major · 12 moderate · 9 minor.
From our pharmacist’s overview on the Anastrozole page
“Activated charcoal carries the one major rating on the anastrozole (Arimidex) list, because it can soak up the drug in the gut and cut how much your body absorbs. For a medicine that treats hormone-sensitive breast cancer by keeping estrogen suppressed, anything that lowers its level deserves real concern, and I would act on this list…”

Where Lavender Cotton and Anastrozole Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.
#1,373 of 1,452 supplements looked up here in the last 7 days
#479 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.
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 Anastrozole 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 Anastrozole
What Is Anastrozole Used For?
Brand name: Arimidex
Anastrozole (also sold as Arimidex) is used in postmenopausal women to treat hormone receptor-positive breast cancer at several stages. This includes early breast cancer after surgery (adjuvant therapy), locally advanced or metastatic breast cancer as a first treatment, and advanced breast cancer that has continued to grow after tamoxifen therapy.
For the second-line use in advanced breast cancer, women whose cancer did not respond to estrogen receptor (ER) testing or who did not respond to tamoxifen rarely benefited from anastrozole.
