Oreganol P73 is oil of wild oregano in an olive oil base, sold as drops and as gelcaps by North American Herb & Spice. People buy it for seasonal immune support.* Then they get it home, put two drops under the tongue the way the label says, and find out it burns like nothing else in the cabinet.
This is the guide for that moment. What P73 actually means, why the drops burn, how to take them so they don't, what the label serving is, how long people usually run it, and who should ask before starting. If you're still deciding whether to buy, the Oreganol P73 product page covers that. This is for once the bottle is in your hand.

What P73 means
P73 is North American Herb & Spice's designation for its oil of wild Mediterranean oregano. In the company's words, the P stands for potency, purity, and phenolic power. The 73 is the average carvacrol percentage of the oil. Carvacrol is the main phenolic compound in oregano oil, and both the regular and the super strength labels print "Natural carvacrol level: 73% plus." The company says the real figure runs from 68 to 78 percent depending on the harvest year.
So the number describes the oregano oil itself, not how strong a drop is. That's where the super strength version comes in. Regular Oreganol P73 oil and Super Strength Oreganol P73 use the same P73 oregano oil, steam distilled rather than solvent extracted and diluted into organic extra virgin olive oil. Both list a two drop serving of 50 mg. The super strength version has a higher share of oregano oil to olive oil inside those drops, which is why it's hotter and why the company sells it as the more concentrated option.
Oil of oregano vs. oregano essential oil
These are not the same product, and mixing them up is the single biggest mistake people make with oregano.
Oil of oregano, which is what Oreganol is, has already been diluted into a carrier oil so a drop or two can go in your mouth. Oregano essential oil, the kind sold for diffusers, is the undiluted distillate. It's for a diffuser or for diluting into a skin oil, not for swallowing. A drop of diffuser oil under the tongue is a bad afternoon, and depending on the brand it may not be food grade in the first place.
Quick way to tell them apart: the Oreganol label lists olive oil as an ingredient and gives a serving size in drops. An aromatherapy bottle usually says "for external use" or "do not ingest" and lists only oregano.
What people use oregano oil for
Oregano is a kitchen herb with a long history of Mediterranean folk use. The oil concentrates two compounds, carvacrol and thymol. They're why it smells the way it does and why it's so strong in the mouth.
What the research supports is narrower than the internet suggests. Carvacrol and thymol are well studied antioxidants in the lab. Most of that work is on the compounds themselves, in test tubes or in animals. Human trials on oregano oil are few and small. So the honest description is a traditional herb with strong antioxidant compounds, used by a lot of people as part of seasonal immune support*, with thinner human evidence than its reputation implies.
That's the frame the label uses and it's the one we use. Oreganol P73 is sold to support healthy immune function and antioxidant activity*, nothing more specific. If you have a specific health concern in mind, that's a conversation for your practitioner, not a bottle.
How to take Oreganol P73 without the burn
The label serving is two drops under the tongue or in juice or water, once a day. Under the tongue is the fastest way to learn how strong it is. Here's the routine most people settle into.
- Start with one drop, not two, for the first few days. The label serving is two. There's no prize for starting there.
- Have your chaser in hand before the drop goes in. A small glass of orange, grapefruit, or tomato juice works better than water. The acidity and sugar cover the taste and the heat fades faster. Water is fine, it just takes longer.
- Under the tongue: tilt your head back a little and let the drop land under your tongue, not on top of it. Hold for 20 to 30 seconds, swallow, drink. On top of the tongue it burns more and lingers.
- Or skip your mouth entirely. Put the drops in a couple of ounces of juice, stir, drink it down, rinse with water. This is the gentlest route and it's right there on the label.
- Take it with food or right after a meal if it bothers your stomach on its own.
- Wipe the dropper, cap the bottle, wash your hands before you touch your face. Oregano oil in the eye is a memorable experience.
Give it three or four days at one drop before moving up to two. Once you know how your mouth reacts, the under the tongue method takes about ten seconds and stops being a thing.
How much, how often, how long
How much: two drops a day is the label serving for both the regular and the super strength oil. Some people stay at one. Taking more than the serving because "it's just an herb" is how people end up with a raw mouth and an unhappy stomach. Stay at or under the serving unless a practitioner who knows your situation says otherwise.
How often: once a day. If you'd rather split it, one drop in the morning and one in the evening, each with juice, is easier on the mouth than two at once.
How long: the label says daily and doesn't set a limit. In practice most people use oregano oil in short runs, a couple of weeks at a time when they want extra seasonal support*, rather than as a year round daily supplement. That's a reasonable default for a strong herb and it matches how it has traditionally been used. If you're thinking about taking it continuously for months, ask your practitioner first.
Who should skip it or ask first
- Pregnant: don't. The oil isn't suitable during pregnancy.
- Nursing: ask your doctor or midwife before starting.
- Kids: Oreganol P73 oil isn't labeled for children, and the label says to keep it out of their reach. Don't improvise a smaller dose of the drops. If a practitioner has suggested oregano for a child, OregaMax capsules (below) are labeled to be opened and mixed into food for young children, which is a milder, whole herb product. Ask the pediatrician either way.
- Mint family allergies: oregano is in the same plant family as basil, sage, mint, thyme, and lavender. If you react to those, skip oregano oil.
- On medication or managing a health condition: the label says to consult a physician first, and that isn't boilerplate. Oregano oil is potent and it hasn't been well studied alongside prescriptions.
Taste tricks and common mistakes
Tricks that actually help: chase with citrus or tomato juice instead of water. Put the drops on a spoonful of honey or a bite of bread if there's no juice around. Stir them into a salad dressing, since the oil was olive oil to begin with. Whatever you pick, have it in your hand before the drop goes in, not after.
The mistakes that come up most:
- Using an aromatherapy oregano essential oil instead of an oil of oregano made for internal use.
- Starting at two drops, or taking "a few" without counting. Count them.
- Dropping it on top of the tongue instead of under it.
- Putting it in hot tea. Heat sends the volatile oils straight up your nose and the burn gets worse, not better. Room temperature juice is the move.
- Taking it on an empty stomach right before bed and then lying down. It can repeat on you. Earlier in the day, with food, is better.
- Rubbing an eye after handling the dropper.
- Using the drops on skin straight from the bottle. The label allows topical use and the oil is already diluted in olive oil, but on skin it's still hot. Mix a drop into a teaspoon of plain olive oil and patch test a small spot first. Keep it away from eyes, lips, and anywhere sensitive.
Drops or gelcaps: which format fits you
North American Herb & Spice makes the P73 oregano in several forms, and they're not interchangeable.
| Format | What's in it | Label serving | Taste | Fits you if |
|---|---|---|---|---|
| Oreganol P73 oil (.45 oz or 1 oz) | P73 oregano oil in organic olive oil | 2 drops daily, under the tongue or in juice/water | Strong, burns neat | You want the fastest route, you don't mind the taste, or you also want to use it on skin |
| Super Strength Oreganol P73 oil (1 oz) | Same P73 oil, more concentrated | 2 drops daily | Hotter still | You've used the regular oil and want more per drop |
| Oreganol P73 gelcaps (60 or 120) | P73 oregano oil in olive oil, inside a tapioca gelcap | 1 gelcap daily with a meal or juice | None | The taste is what's stopping you, or you travel |
| Super Strength gelcaps (60 or 120) | The concentrated oil in a gelcap | 1 gelcap daily with a meal | None | You want the stronger version without the burn |
| OregaMax capsules (90) | Whole wild oregano herb with sumac, garlic, and onion. Not the oil. | 1 capsule daily. Label allows opening it into food for young children. | Herby, mild | You want the crude herb rather than the concentrated oil, or a practitioner has suggested oregano for a child |
| SinuOrega nasal spray (1 oz or 2 oz) | Spring water, sea salt, wild oil of oregano, clove, sage, and bay leaf oils | 1 squirt each nostril, as needed | Stings briefly | You want oregano for your nose, not your mouth |
The gelcaps are the answer for most people who've tried the drops once and decided never again. Same oil, no burn, and the label serving is one gelcap with a meal. The trade off is practical rather than chemical: a gelcap can't go under the tongue and can't be split into a one drop start. If you want oregano oil in a capsule but not the P73 blend, NOW Foods Oregano Oil comes enteric coated and Gaia Herbs Oil of Oregano is a liquid extract in a capsule.
OregaMax is the odd one out. It's the dried herb, plus sumac, garlic, and onion, in a capsule. It isn't concentrated oil, so it's much milder, and it's the only one of the lineup whose label speaks to young children at all.
All of these sit on our immune support shelf with the rest of the seasonal lineup.
The short version
Start at one drop, under the tongue or in juice. Chase it with something citrus. Move to the two drop label serving after a few days, and don't go past it. Run it in short stretches rather than forever, keep it away from your eyes, and check with your practitioner if you're pregnant, nursing, on medication, or thinking about giving it to a child. If the taste is the only thing in the way, the gelcaps are the same oil without the drama.
