Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Glossy Privet and Felodipine 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 label for Felodipine states a food rule worth keeping to.

Glossy Privet and Felodipine

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 Felodipine and Glossy Privet 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.

Glossy Privet safety at a glance

Glossy Privet overall Use caution Generally used in small amounts in traditional formulas, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid No reliable safety data exist, so avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Felodipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Felodipine is filed under 5 classifications — including calcium channel blockers, antihypertensive drugs, cytochrome p450 3a4 (cyp3a4) substrates. Glossy Privet has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Felodipine’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.

What to actually watch for

What Glossy Privet Itself Has Been Linked To

This is not an interaction — nothing below involves Felodipine. It is the side-effect record for Glossy Privet on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Glossy Privet, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    “None reported. However, respiratory allergies (allergic rhinitis, asthma) and cross-allergenicity have been reported with the pollen of other Oleaceae species including common privet (Ligustrum vulgare), olive, ash, and lilac.”

Everything above comes from the Natural Medicines adverse-effect record for Glossy Privet — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Felodipine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Felodipine column appears here.

How to take them

Some Felodipine Products Have a Food Rule — Glossy Privet Should Not Break It

At least one FDA label for a product containing Felodipine says to take it on an empty stomach. Most supplements — Glossy Privet included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Felodipine on its own and move Glossy Privet to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Felodipine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Felodipine should regularly be taken either without food or with a light meal (see CLINICAL PHARMACOLOGY, Pharmacokinetics and Metabolism ).

From the Dosage and Administration section of the FDA label we read for Felodipine — where that label names a specific product, the instruction is that product's. See the Felodipine drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Glossy Privet

What is Glossy Privet?

  • Liver and kidney support in traditional medicine
  • Immune support
  • Anti-aging and general tonic
  • Blurred vision and dizziness
  • Premature graying of hair

Glossy Privet (Ligustrum lucidum) is a fruit long used in Traditional Chinese Medicine, often combined with other herbs as a liver and kidney 'tonic.' Most of the research is from laboratory and animal studies, so its benefits in people are not well proven. Because human safety data are limited, talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Ligustrum lucidum · Oleaceae · Ripe fruit (berries) · Dried fruit, decoctions (teas), powders, capsules, tinctures, and herbal formulas

An interaction check asks whether these two react with each other — it does not ask whether Glossy Privet is a good idea for someone in your situation. Here is what our Glossy Privet record says about it on its own.

Glossy Privet: dosing

There is no well-established, standardized dose of Glossy Privet for any condition. Traditional use is usually as part of a multi-herb decoction or formula prepared by a practitioner, rather than as a single supplement.Because products vary widely in strength and quality, the safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Glossy Privet and Felodipine Together: Common Questions

Is it safe to take Glossy Privet with Felodipine?
We do not list a known interaction between Glossy Privet and Felodipine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Glossy Privet and Felodipine at the same time of day?
At least one FDA label for a product containing Felodipine says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Felodipine on its own and move Glossy Privet to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Glossy Privet and Felodipine combination checked?
Interactions in our licensed database are recorded against drug classes. Felodipine is filed under 5 classifications, and Glossy Privet has documented interactions with 1 drug class — none of Felodipine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Glossy Privet interact with any other medications?
Yes. Glossy Privet has 1 documented drug interaction in our database — Felodipine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Felodipine interact with any supplements?
