What is this page for?

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

But these pages have grown well beyond that into a full monograph — what Honeysuckle 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

Honeysuckle Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Honeysuckle drug interaction appears low for most people. None of the listed interactions are rated major, and every one of them stems from a single theoretical concern that has not been confirmed in people.

Interactions deserving the most attention

The one area worth watching is bleeding risk. Lab research shows that plant compounds in honeysuckle may reduce the ability of platelets to clump together, which raises a theoretical concern for anyone taking anticoagulant or antiplatelet drugs, such as blood thinners. This effect has only been seen in laboratory studies, not in humans, so we view it as a precaution rather than a proven problem. Still, because bleeding risk is closely monitored in people on these medicines, it deserves a mention.

What the rest of the list means

The long list of interacting medications can look worrying, but it reflects one theoretical bleeding concern applied across the many drugs that affect clotting. No human studies have shown that honeysuckle actually causes meaningful changes when combined with these medicines, so the number of listed drugs overstates the real-world risk for most people.

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.

Honeysuckle: Uses, Safety & Side Effects

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

The bottom line

Honeysuckle, especially Japanese honeysuckle flower (Lonicera japonica), is a staple of traditional Chinese medicine used mainly for colds, sore throat, and inflammation. Modern human evidence for these uses is limited, so it should be seen as a traditional remedy rather than a proven treatment. It is generally well tolerated as a tea, but talk to your pharmacist or doctor before using it, especially if you are pregnant, nursing, or taking other medicines.

Scientific name: Lonicera japonica
Family: Caprifoliaceae
Part used: Flowers (flower buds), and sometimes stems and leaves
Common forms: Tea, dried flower buds, capsules, tinctures, topical preparations, and combination herbal formulas

People commonly use it for

Colds and sore throat
Fever
Inflammation
Skin rashes and sores
Digestive upset

Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.

Safety at a glance

OverallUse caution

Often used as a tea with few reported problems, but high-quality safety data in humans is limited.

PregnancyBest avoided

Not enough safety information, so it is best avoided during pregnancy.

BreastfeedingBest avoided

Not enough safety information, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

Overview

Honeysuckle is a group of climbing or shrubby plants in the Lonicera family. The most commonly used type in herbal medicine is Japanese honeysuckle (Lonicera japonica), whose flower buds are dried and used. In traditional Chinese medicine the flower is called "jin yin hua," which means "gold and silver flower" because the blossoms change color as they age.

Honeysuckle grows widely across Asia and has spread to many other parts of the world, including North America, where some species are considered invasive. People most often take the dried flowers as a tea, but it also comes in capsules, tinctures, and combination herbal blends.

Traditionally, honeysuckle has been used to help with colds, sore throats, fevers, and skin problems. It is important to know that long use in tradition does not prove that it works for these conditions.

How it works

Honeysuckle flowers contain several plant compounds that researchers have studied, including chlorogenic acid, luteolin, and other flavonoids and iridoids. These are antioxidants that may reduce inflammation in laboratory settings.

In test-tube and animal studies, honeysuckle extracts have shown anti-inflammatory, antioxidant, and some antimicrobial activity. The idea is that these compounds may calm the body's inflammatory response and slow the growth of certain germs.

It is important to remember that these mechanisms are mostly based on laboratory and animal research. What happens in a test tube does not always happen in the human body, and the amounts used in studies may be much higher than what is in a cup of tea.
