Not all Oil of Oregano is created Equal; Which one should you be using

by Sean Martu

Oil of oregano is one of the most popular natural substances within the global alternative health community. Oil of oregano can be used internally or externally, but it’s primarily used to eradicate viruses, bacteria, and fungal infections. I have read anecdotal testimonies of it ridding the body of cancer in both people and animals. There are hundreds if not thousands of research articles on Pubmed elucidating the therapeutic properties of Oil of Oregano and its isolates. But not all oregano is the same, which type of oil of oregano should people be using, and which ones should we avoid?

Which subspecies of oregano should we be using?

Unfortunately, many companies are taking advantage of the popularity of oil of oregano and are marketing oregano with inferior medical therapeutic properties. There are many subspecies of oil of oregano on the market, such as Origanum majorana, Origanum x majoricum, Origanum syriacum, and Origanum vulgare.

Origanum vulgare is the subspecies you want to use, this particular subspecies has the highest concentration of natural carvacrol, the phytochemical that possesses the most bioactive activity within the plant.

Never buy oil of oregano from a company which doe’s not disclose the subspecies they are using on their ingredient label. If they are ambiguous about it, they are most likely using an inferior oregano subspecies.

Avoid synthetic Carvacrol

Avoid like the plague companies advertising that their carvacrol content is in the 80 – 90 % range or higher. These companies are adding synthetic carvacrol to their oil, which is going to debase the synergistic relationship with the other phytochemical compounds in the oil and reduce its efficacy.

Which is better Organically grown or Wild-harvested?

When it comes to oregano, wild-harvested is vastly superior to organically or conventionally grown oregano. Oregano thriving in the high mountain harsh environment of the Mediterranean has a much higher concentration of its main active compounds such as carvacrol and thymol. Oregano thriving in the high rocky mountains is a powerful plant, and the carvacrol levels can be detected up to 84% but more common in the 70% to 78% range. The harsher the environment the plant exists in, the more the plant enriches itself with its phytochemicals for survival.

Organically grown carvacrol in a protected environment with abundant watering is not going to have these phytochemical levels, because the plant is being “pampered” and will not produce the same amount of active phytochemicals for survival.

Conventionally grown oregano, not only will have the same issues as the organically grown oregano, but the plant will also absorb the harmful fungicides, pesticides, and herbicides used in cultivation. Many of these fungicides, pesticides, and herbicides are carcinogenic and endocrine disrupters.

Should I use essential oil or prediluted oil?

Never use the essential of oregano undiluted externally or internally, it will burn a hole right through you. Always dilute Oregano of Oil at least 3:1 with any good carrier oil. Using a prediluted oil is all about convenience and experience, some people prefer making their own oil, others do not want to bother with the process. So it’s up to the individual which they prefer to do.

What are some of the uses of Oil of Oregano?

• cellular health (antioxidant)
• tooth and gum support (analgesic/antibacterial)
• immune support (antibacterial/antiviral)
• toe and nail health (antifungal)
• cuts and burns (antibacterial)
• surface sterilizer (antimicrobial/germicidal)
• sinus support (antifungal)
• bone and joint support (anti-osteoclastic)
• bug/mosquito bites (anti-venom)
• vaccine toxicity (detoxicant)
• throat support (antiseptic)
• digestion and bowel support (anti-parasitic)
• urinary tract support (antibacterial)
• respiratory support (antiviral)
• yeast support (antifungal)

See my article “Oil of oregano: the only antibiotic or antiviral you’ll ever need“.

What is the P73 standard?

The P73 standard was created by the company North American Herb. It compromises of:

  • never standardized
  • only use full-spectrum
  • GMO-free
  • never using chemical or heat extraction
  • free of all synthetics including anything petrol-based
  • additive-free
  • free of all synthetics
  • predominantly wild, always unadulterated
  • no Magnesium stearate
  • no Calcium stearate
  • no Aspartame
  • no Talc
  • no Titanium dioxide
  • no Soy (GMO) as lecithin, protein powder, etc.
  • no Corn derivatives (GMO) as ascorbic acid, corn starch, corn syrup, citric acid, etc.
  • no Sodium benzoate or Potassium Sorbate
  •  Natural Flavors
  • no Sugar
What does standardized mean?

Standardized products are when a product contains a guaranteed amount of a certain botanical constituent. Typically extracted/isolated with chemical solvents such as:
• Hexane
• Benzene
• Acetone
• Methyl Chloride
What happens to the synergistic properties of the plant when we standardize the celebrated constituent? The natural balance of the plants’ phytochemicals becomes convoluted, thereby disorienting its nature given therapeutic effect.

North American Herbs P73 Oil of Oregano is a vastly superior product, as it possesses all of the above-mentioned requirements I outlined for a superior potent oil of oregano. I use it all the time and recommend it to everyone I know. I have not only read hundreds of research articles on the therapeutic effects of it on PubMed, but I have experienced and seen the miracles with my own eyes. You can purchase on my website North American Herbs Oil of oreganos’ .45 oz or the 1oz dropper bottle.
