Chrysanthemum Drug Interactions, Uses, Effectiveness, Safety & More

What is this page for?

First and foremost: how Chrysanthemum interacts with medications. The heart of this page is the interaction list — every drug Chrysanthemum is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Chrysanthemum is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Chrysanthemum: Uses, Safety & Side Effects

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Reviewed July 2026 ·

The bottom line

Chrysanthemum flowers are most often used as a soothing tea in traditional Chinese medicine and as a folk remedy for eye irritation, colds, and minor inflammation. Solid human evidence for these uses is limited, so it should be seen as a pleasant traditional drink rather than a proven treatment. People allergic to ragweed and related plants, and those who are pregnant or breastfeeding, should be cautious and talk to a pharmacist or doctor first.

Scientific name: Chrysanthemum morifolium
Family: Asteraceae
Part used: Flowers (dried flower heads)

Overview

Chrysanthemum is a flowering plant in the daisy (Asteraceae) family. The dried flower heads, often from Chrysanthemum morifolium, are the part most commonly used for health purposes. These flowers are widely grown in East Asia and have a long history of use in traditional Chinese medicine.

The most popular way to use chrysanthemum is as a fragrant herbal tea, sometimes on its own and sometimes blended with other herbs. It is also available as dried flowers, capsules, extracts, and in topical products. In traditional medicine it is considered a 'cooling' herb used to clear heat from the body.

How it works

Chrysanthemum flowers contain natural plant compounds such as flavonoids, phenolic acids, and other antioxidants. In laboratory studies, these compounds show antioxidant and anti-inflammatory activity, which is part of why the plant is traditionally used to soothe irritation.

It is important to remember that most of this research is from test-tube or animal studies. Effects seen in a lab do not always translate into meaningful benefits in people, and the amounts used in research may differ greatly from what you get in a cup of tea.
