Oreganol P73 Super Strength – oregano oil drops, 13.5 / 30 ml wild oregano oil P73 • organic extra virgin olive oil • 2 drops daily • food supplement

Steam distillation and oregano’s aromatic compounds

NAHS extracts oregano essential oil by steam distillation. Steam releases volatile compounds from the plant material. Cooling condenses the vapour, allowing the essential oil to separate from the water. Its composition differs from dried oregano leaf and from a herb infused in oil.

NAHS does not extract its oregano using hexane or butane. The oil retains a naturally occurring mixture of aromatic constituents, rather than consisting of isolated carvacrol added to olive oil.

Distillation conditions also affect the oil’s composition. A 2023 study of Greek oregano examined how time, pressure and temperature influence oil yield and volatile constituents. The study examines processing rather than Oreganol’s health effects or its specific manufacturing methods.

Checking essential oil composition and authenticity

• Gas chromatography separates individual aromatic constituents. The wider chemical profile provides information beyond a single carvacrol percentage. Calculating carvacrol in a finished dose also requires the proportion of oregano oil in the blend.
• Isotope analysis can help distinguish natural aromatic compounds from synthetic material. A 2006 analytical study examined carvacrol, thymol and other essential oil constituents. It is not a certificate for a specific NAHS batch or evidence of a health benefit.

Two oils with a pronounced herbal taste

Oregano essential oil has an intense herbal aroma and taste. Super Strength has a pronounced herbal taste, even with olive oil as the carrier.

The formula contains oregano oil and olive oil. There is no alcohol, sweetener or added flavouring. Oil does not dissolve in water; stirring it into a drink does not create a stable emulsion.

• Follow the two-drop daily dose for Super Strength. They are different from undiluted oregano essential oil.
• If the herbal taste does not suit you, compare Super Strength softgels. Capsules have their own ingredients and daily dose; do not estimate a capsule dose from the number of drops.

Original Strength, Super Strength, OregaUltra and H2Orega

Original Strength and Super Strength contain P73 oregano oil in olive oil, in different proportions. Both 30 ml labels declare 50 mg of the complete blend per two drops. Super Strength has a higher oregano-to-olive-oil proportion, so the 50 mg blend weight alone does not show the difference in concentration. Oreganol P73 Original Strength is the standard oil formula; Super Strength contains a greater proportion of oregano oil.

OregaUltra differs in its oregano ingredient and the other oils in the blend. It uses oregano oil with a declared 84% carvacrol content, blended with organic extra virgin olive oil and black seed oil. Two drops contain 50 mg of all three oils together. The 84% figure describes the oregano oil before blending, rather than the contents of the whole bottle or daily dose.

H2Orega is a water-miscible, micellised form of P73. Micellisation allows the oil constituents to disperse in water, so the drops can be mixed into a drink. Its recommended five-drop dose contains 100 mg of the micellised blend. Choose it when you want oregano that mixes with water or juice; Original Strength, Super Strength and OregaUltra are oil blends. Drop counts and different blend weights do not establish equivalent oregano doses.

What does P73 mean?

• P stands for potency, purity and phenolic power. This explains NAHS’s product designation; it is not a separate certification.
• 73 refers to an average of approximately 73% carvacrol in the oregano oil itself. Natural levels vary between harvests. It does not mean that the finished drops contain 73% carvacrol or that every batch has an identical percentage.

Why 50 mg does not mean 50 mg of oregano oil

• The 30 ml label declares 50 mg of the whole oil blend per two drops. That weight includes the olive oil carrier.
• The separate oregano oil and carvacrol amounts are not stated. Multiplying 50 mg by 0.73 therefore does not give the carvacrol content.

Understanding the 60:1 comparison

• NAHS uses 60:1 when comparing oregano oil with dried oregano leaf. This is not the oregano-to-olive-oil ratio or a carvacrol percentage.
• No method is published for calculating the equivalent weight of dried herb. We therefore do not use this ratio to calculate grams of dried herb or a multiple of health effects.

A higher oregano proportion is not a measure of health effects

• Super Strength identifies a different ingredient ratio from Original Strength. It does not mean a higher recommended daily dose or a clinically established increase in effectiveness.
• A single constituent’s percentage is insufficient to compare finished supplements. The full formula, amount per daily dose and directions all need to be considered.

Ingredients: wild Mediterranean oregano oil P73, organic extra virgin olive oil. The 50 mg declaration covers both oils together. Their ratio and the carvacrol amount per daily dose are not stated. There is no established Nutrient Reference Value for this oil blend.

How to Use

Take 2 drops daily. Do not exceed the recommended daily dose. Follow the directions on your bottle.

Do not adjust the dose according to taste intensity. A higher oregano proportion is not a reason to take more drops or add other oregano products.

Bottle sizes and dose count

The dose count applies to the 30 ml bottle; it is not a recommendation to take the drops continuously for that length of time. For other bottle sizes, follow their own packaging information. Observe the best-before date.

Storage

Store in a cool, dry place away from direct sunlight and heat. Close the bottle after use and keep out of reach of young children.

Technical research on processing and ingredient analysis

• How steam-distillation conditions affect Greek oregano oil (2023)
• Isotope analysis of carvacrol and thymol in essential oils (2006)

These are processing and analytical studies, rather than clinical evaluations of the finished drops. They explain ingredient processing and authentication; they do not establish Oreganol’s health effects or report tests on a specific NAHS batch.

From ingredient to finished supplement

NAHS develops and manufactures its own supplements. Founder Judy K. Gray remains personally involved in sourcing and formulation, working with the brand’s development, manufacturing and quality-control teams.

Oregano was just the beginning

The range began with Oreganol P73. Judy K. Gray has since developed more than 400 formulas for NAHS and its sister brand, Physician’s Strength, which has a separate range for healthcare practitioners.

The wholefood approach

NAHS aims to retain naturally occurring compounds together. For pressed oils, that means considering the seed’s accompanying compounds as well as its fatty acids; for oregano, the essential oil’s wider aromatic profile. The plant and the part used determine how it is processed.

Beyond oregano

Black seed, turmeric, chaga and wild berries sit alongside fish oils in the range. They appear in capsules, drops, powders and drink blends, each with its own ingredients and directions.

Long-standing relationships at source

NAHS works with established local partners and harvesters. Its wild oregano is picked by hand in the Turkish mountains; other ingredients come from regions including Peru and northern Canada. Knowledge of local plants, harvests and growing conditions informs both ingredient selection and processing.

More than a buying relationship

NAHS has helped fund wells, schools and community facilities. Its Strong Community Causes programme also supports selected projects nominated by customers.

In-house research & development

The development team selects the ingredients, extracts and any carriers for each formula. It also determines the final format, from liquid oils to capsules and powders.

Made in Lake Forest, Illinois

NAHS has its own manufacturing facilities in Lake Forest, near Chicago. Liquid products are bottled on site under the supervision of the quality-control team.

Checks at both ends of production

Incoming ingredients and finished products are tested for identity, levels of selected constituents and unwanted impurities. Quality control continues beyond receipt of the raw material.

Processing to suit the ingredient

Cold pressing, steam distillation, CO₂ extraction, juicing and milling serve different purposes. Seeds yield pressed oils, while distillation can separate essential oils from aromatic herbs.

Knowing the source

Long-standing partners and local harvesters connect NAHS with the places its ingredients come from. Both the plant species and its growing environment inform the choice of raw material.

GMP & facility certifications

Manufacturing follows GMP principles. The facility holds organic, Kosher and Halal certifications; these do not automatically apply to every individual product.
