Yarrow + Emapalumab-Lzsg
Emapalumab-Lzsg brand name: Gamifant.
We found no known interaction between Yarrow and Emapalumab-Lzsg 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.
Yarrow and Emapalumab-Lzsg
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 Emapalumab-Lzsg and Yarrow 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.
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.
Yarrow safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Emapalumab-Lzsg
Interactions in our licensed database are recorded against drug classes, not just single drug names. Emapalumab-Lzsg is filed under a single classification — immunosuppressants. Yarrow has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Emapalumab-Lzsg’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

About Yarrow
What is Yarrow?
- Wounds and minor bleeding
- Digestive upset and cramping
- Colds, flu, and fever
- Skin conditions
- Menstrual discomfort
Yarrow is a traditional herb long used for wounds, digestive complaints, and colds, but high-quality human studies are very limited, so its benefits are not well proven. It is generally used short-term, and people who are pregnant, breastfeeding, or allergic to ragweed and related plants should avoid it.
Achillea millefolium · Asteraceae · Aerial parts (leaves, flowers, and stems) and essential oil · Tea, tincture, capsules, dried herb, topical creams or ointments, and essential oil
An interaction check asks whether these two react with each other — it does not ask whether Yarrow is a good idea for someone in your situation. Here is what our Yarrow record says about it on its own.
Yarrow: dosing
There is no official, standardized dose for yarrow. Traditional use includes teas made from the dried herb, tinctures, and capsules, as well as creams applied to the skin.Because product strengths vary widely, the safest approach is to follow the directions on the product label and not exceed them. Yarrow is intended for short-term use, not long-term daily use.
