Created by North American Herb & Spice, Oreganol P73 is said to be the first edible, and highest quality, oregano oil.
Oregano, or wild marjoram, is commonly used to flavor Mediterranean and Mexican cuisines. It has been recognized for its aromatic properties since ancient Greece. Hippocrates even used oregano as an antiseptic and cure for stomach ailments. However, oregano was almost unheard of in the US until soldiers returning from Italy during World War 2 raved about the ingredient.
Oreganol P73 is derived from wild, mountain-grown, Mediterranean oregano, free from chemicals and pesticides. To process it, manufacturers use cold pressing technique and steam distillation to extract its key components. It is then emulsified, or bound, with extra virgin olive oil. No chemicals are used during the extraction process.
Oregano, and subsequently Oreganol P73, is rich in vitamin K, manganese, iron, and calcium.
It can be applied topically or taken orally.
Oregano oil is a rich source of volatile oils thymol and carvacrol, which are largely responsible for oregano oil’s antimicrobial effects.
In vitro studies suggest oregano oil’s thymol and caravcrol compounds interact with surface protein, altering bacterial cell surfaces. This compromises the cell structure and inhibits bacterial growth.
Other studies show oregano oil kills at least 30 different harmful bacteria strains, including coronoaviruses, which are the second most common viruses that trigger the common cold.[5-12]
Oregano also contains chemicals that may reduce coughs and spasms, as well as improve digestion and bile flow.
Toxicity studies indicate oregano oil is safe to use and is not associated with serious side effects or negative health outcomes.
Mild side effects include upset stomach.
Women who are pregnant or breastfeeding should not use Oreganol P73 capsules without consulting a doctor first.
Oregano may trigger an allergic reaction in individuals allergic to lamiaceae herbs such as basil, hyssop, lavender, and mint.
Oregano has a moderate interaction with lithium, a diuretic. Taking oregano may decrease the body’s ability to eliminate lithium, which could increase side effect risk. If you are taking lithium tablets, talk to your doctor about adjusting your lithium dose.
Clinical studies have not yet verified a safe and effective dose, and usage instructions vary depending on the product.
However, when using 250mg Oreganol P73 capsules, many experts suggest the followin dosages:
- Colds, flu, acute bronchitis, and sinusitis– 2 capsules every 4 hours at the earlies sign of illness to minimize symptoms and duration.
- Chronic bronchitis and chronic asthma– 2 capsules twice daily until condition improves, then reduce or eliminate dosage.
- Chronic mono and chronic fatigue– 2 capsules twice per day along with other immunity boosting supplements.
- Candida and yeast infections– 2 capsules 3 times daily until significant improvement. Then, lower maintenance dosage can be taken until symptoms resolve.
- Duodenal and gastric (stomach) ulcers– 3 capsules 3 times daily in conjuction with other medicines aimed at killing the H. Pylori bacterium.
- Acne and rosacea– 2 capsule twice daily. A topical oregano oil cream may be applied at night for additional benefits.
Additional experts suggest taking 200mg oregano oil 3 times daily for 6 weeks to eliminate intestinal parasites.
If oregano oil is consumed continuously for longer than one month, it is prudent to ingest functional foods containing live cultures of friendly bacteria such as yogurt. This maintains ideal begnin intestinal bacterial levels.
