Lavender Cotton and Ranibizumab

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 Ranibizumab 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 Ranibizumab, 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.

What Ranibizumab’s Own FDA Label Lists

This is not an interaction — none of it involves Lavender Cotton. These are the most notable effects listed in the ADVERSE REACTIONS section of Ranibizumab’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • An irregular heartbeat Worth acting on
  • Kidney problems Worth acting on
  • Bleeding or bruising Worth acting on mentioned in 4.0% of FDA reports for Ranibizumab
  • Anemia Worth acting on
  • A higher chance of infection Worth acting on
  • Blurred vision mentioned in 21.1% of FDA reports for Ranibizumab
  • Eye irritation or redness
  • Dry eyes
  • Heartburn
  • Numbness or tingling

Showing the 10 most notable of 16 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ranibizumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 26,416 voluntary FDA FAERS reports for Ranibizumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Lavender Cotton’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Lavender Cotton side to compare — that is a limit of the record, not a statement that Lavender Cotton has no side effects.

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 Ranibizumab 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.
