Why it’s Pravé Bio
We chose OregaRESP for its wild P73 oregano, sage, cumin and cinnamon bark oils. Extra virgin olive oil carries the four aromatic botanical oils. Six drops contain 225 mg of the complete blend; the recommended daily dose contains 450 mg.
Wild oregano and an unrefined carrier oil. NAHS selects edible oregano species from Mediterranean mountain habitats for P73. The aromatic oils are diluted in extra virgin olive oil, without an alcohol base. The liquid can be added to juice or food.
NAHS selects and processes its ingredients to retain their natural composition. The aim is to preserve naturally occurring compounds together rather than focus on a single isolated constituent. Steam distillation extracts oregano’s aromatic compounds, including carvacrol and thymol. Extra virgin olive oil retains other naturally occurring olive compounds alongside its fatty acids.
What P73 means
- P73 is NAHS’s own designation for a blend of oils from selected edible wild oregano species. It is neither a botanical name nor a quality grade.
- P stands for potency, purity and phenolic power: the oil’s strength, purity and naturally occurring phenolic compounds.
- 73 refers to an average of approximately 73% carvacrol in the original oregano oil blend.
- The percentage describes the oregano oil before it is mixed with a carrier. It does not state the carvacrol concentration in the finished drops.
Suitable for
Important information
- Do not exceed the recommended daily dose.
- Food supplements should not replace a varied, balanced diet. A healthy lifestyle is also important.
- Keep out of reach of young children.
- Consult a doctor or pharmacist before use if you take medication, have a medical condition, are pregnant or are breastfeeding.
- Do not take if you are allergic to any ingredient. Consult a paediatrician before giving to a child. Stop use if irritation occurs.

P73 oregano and cinnamon: selection and extraction
P73 starts with the selection of wild oregano. NAHS uses several edible species from Mediterranean mountain habitats, selected for their aromatic profile, with substantial carvacrol and low thymol levels. In OregaRESP, their essential oils are blended with extra virgin olive oil, sage, cumin and cinnamon.
Steam distillation concentrates oregano’s volatile aromatic compounds. Steam carries these compounds from the herb. As the vapour cools and condenses, the essential oil separates, retaining carvacrol, thymol and other naturally occurring compounds. Fibre and other non-volatile constituents remain behind.
The drops use cinnamon bark oil. Cinnamon is present as an aromatic oil. For OregaRESP oil softgels, NAHS uses cinnamon oleoresin obtained by CO₂ extraction. The two ingredients represent different ways of processing cinnamon bark.
Cinnamon bark oil and CO₂ extract: the difference
- Cinnamon bark oil in the drops. This liquid blend contains aromatic oil rather than ground bark. Ground cinnamon also retains fibre and other non-volatile plant constituents.
- CO₂ oleoresin in the softgels. Under controlled pressure and temperature, carbon dioxide extracts aromatic compounds from the bark. Extraction conditions affect the proportions of cinnamon compounds in the resulting extract.
Beyond carvacrol: oregano’s aromatic profile
- Phenolic constituents. Carvacrol and thymol are phenolic monoterpenes within the broader aromatic mixture obtained by distilling the herb.
- Other terpenes. Oregano essential oils also contain p-cymene and γ-terpinene. Alongside carvacrol and thymol, they form the broader aromatic profile of the distilled oil.
- Plant selection shapes the finished oil. Different oregano species have different proportions of aromatic compounds. P73 uses selected edible wild species, so the plants’ natural composition helps determine the essential oil’s profile.
Oil drops, tinctures and micellised liquids
OregaRESP uses extra virgin olive oil as its carrier. The aromatic ingredients are diluted in this oil base. The carrier also affects how you take the product: an oil blend behaves differently from an alcohol extract or a liquid processed to disperse in water.
- Olive oil: the fat-based carrier. It consists mainly of fatty acids bound in fats. It carries the aromatic ingredients and is included in the declared blend weight.
- Essential oils: concentrated aromatic compounds. Oregano and the other botanical oils supply volatile plant constituents. Their composition differs from pressed olive oil and whole dried herbs.
- Tinctures: extraction into alcohol. Alcohol tinctures extract plant compounds into alcohol or a mixture of alcohol and water. OregaRESP has an oil base, with no alcohol in its ingredients.
- Micellisation: dispersing oil in water. H2Orega is processed this way. OregaRESP is not micellised, so its oils do not dissolve in water.
Extra virgin olive oil is obtained mechanically, without refining. It retains naturally occurring olive constituents, including phenolic compounds, alongside its fats. These differ from the aromatic compounds in distilled oregano oil.


OregaRESP drops, oil softgels or powder capsules?
OregaRESP drops contain four aromatic botanical oils in an olive oil base. The liquid dose can be added to juice or food. Six drops contain 225 mg of the blend, giving 450 mg at the recommended twice-daily dose.
OregaRESP 4-in-1 oil softgels contain 140 mg of the blend per capsule. A soft, plant-based tapioca shell seals the liquid filling inside. When swallowed intact, it limits direct contact between the oil and your tongue. The cinnamon ingredient is CO₂ oleoresin.
OregaRESP 6-in-1 powder capsules contain oil extracts dried at low temperatures. The blend includes oregano, cumin and sage extracts, cinnamon CO₂ oleoresin, whole oregano herb and ginger. Each capsule contains 450 mg of the blend, with concentrated aromatic extracts and the wider range of constituents found in whole herbs.
Oreganol P73 Original Strength drops contain oregano oil in an olive oil carrier without sage, cumin or cinnamon. For children and adults sensitive to strong flavours, NAHS offers Orega-Cinn: oregano and cinnamon in a blend with water, syrups and fruit ingredients.
Why the blend includes extra virgin olive oil
- A carrier for concentrated essential oils. Olive oil dilutes the aromatic oils. It is included in the declared blend weight of 225 mg per six drops.
- Fatty acids and aromatic compounds. Olive oil consists mainly of fats, whereas oregano essential oil contains volatile compounds extracted by distillation. They contribute different types of compounds to the blend.
- Extraction without refining. Extra virgin olive oil is obtained by mechanical processes. It retains naturally occurring olive constituents alongside its fatty acids.
Cumin and sage: the other botanical ingredients
- Cumin, rather than black seed. Cuminum cyminum is botanically distinct from caraway and black seed. The black seed oil used in other NAHS products comes from Nigella sativa.
- Wild sage oil. Oregano and the other spice ingredients are accompanied by aromatic sage oil. The liquid blend does not contain sage leaves.
- What the blend weight includes. The 225 mg figure covers all four aromatic oils and the olive oil carrier. NAHS does not list their individual proportions.
Strong flavour: take with food or choose capsules?
- With juice or food. NAHS recommends these as ways to take its multi-spice blend. The drops can be taken with or without meals.
- Oil sealed inside a capsule. Swallowing OregaRESP softgels intact limits direct contact between the filling and your tongue. A herbal aftertaste or burping may still occur.
- A milder, fruity liquid. Orega-Cinn contains water, yacon syrup, goldenberry syrup and raspberry ingredients. It does not contain the same four botanical oils as OregaRESP.
Why NAHS offers whole oregano herb as well as oil
- Whole herb in OregaMax. OregaMax contains dried wild oregano, sumac, garlic and onion. Using the whole oregano herb retains non-volatile constituents that do not pass into the distilled essential oil.
- Alongside oregano oil. NAHS recommends taking OregaMax with Oreganol P73 oil. This provides whole oregano herb alongside its distilled aromatic compounds.
