Poplar + Progestin, Oral Contraceptive
Progestin, Oral Contraceptive brand name: Slynd.
We found no known interaction between Poplar and Progestin, Oral Contraceptive 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.
Poplar and Progestin, Oral Contraceptive
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 Progestin, Oral Contraceptive and Poplar 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 Poplar at all — not against Progestin, Oral Contraceptive, 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.

From our pharmacist’s overview on the Progestin, Oral Contraceptive page
“If you take Slynd, a progestin-only birth control pill, treat this list with real care, because anything that lowers the hormone level can weaken protection against pregnancy. Slynd is cleared by the CYP3A4 enzyme, and nearly all 139 ingredients on file touch that pathway one way or another.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Poplar 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 Poplar reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Poplar and Progestin, Oral Contraceptive 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 Poplar
What is Poplar?
- Minor pain and fever
- Arthritis and joint discomfort
- Minor skin wounds and irritation (topical)
- Coughs and sore throat
- Inflammation
Poplar comes from trees in the Populus genus and has a long history in folk medicine for pain, inflammation, and minor wounds, partly because its bark and buds contain salicin (a salicylate similar to the building block of aspirin). High-quality human studies are limited, so its true effectiveness is uncertain. Talk with your pharmacist or doctor before using it, especially if you are sensitive to aspirin.

An interaction check asks whether these two react with each other — it does not ask whether Poplar is a good idea for someone in your situation. Here is what our Poplar record says about it on its own.
Poplar: dosing
There is no well-established standard dose for poplar. The right amount depends on the product, the part of the plant used, and how it is prepared (tea, tincture, capsule, or topical).The safest approach is to follow the directions on the product label and not exceed them.

About Progestin-Only (drospirenone) Oral Contraceptives
What Is Progestin-Only (drospirenone) Oral Contraceptives Used For?
Brand name: Slynd
-
Progestin-only (drospirenone) oral contraceptives are used to prevent pregnancy. Progestin is a female hormone. It works by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus. Progestin-only oral contraceptives are a very effective method of birth control, but they do not prevent the spread of of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.
