BOTANICAL IDENTITY
The right name is the first step.
Also known as: Marjoram
Origanum majorana must not be confused with Origanum vulgare.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
01 · UNDERSTAND
Properties & uses.
Digestion
Traditional use of the herbal tea for bloating and flatulence.
Read the sourceIrritated skin around the nose
Traditional use of suitable topical preparations.
Read the sourceThe traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.
02 · UNDERSTAND THE ACTION
How does the plant act?
Sweet marjoram is documented for two very different traditional uses: oral digestive use in adults and a specific topical preparation around nostrils irritated during a cold. Cell experiments must not expand these indications. An infusion used in a laboratory, after concentration and technical preparation, does not demonstrate the same effects as drinking a cup or applying an ointment.
Bloating and mild digestive spasms
This use of the flowering aerial part is based on tradition. It does not prove treatment of a chronic digestive disease.
Read the referenceIrritated skin around the nose
A particular external formulation has a traditional use on the skin around the nose. This does not justify putting essential oil into the nostrils.
Read the referenceCell growth in the laboratory
Concentrated preparations influenced the growth of certain cell lines in experiments reviewed by EMA. The result varied by cell line.
Read the referenceWhat this means for preparation.
Distinguish an adult digestive preparation from an external formulation with its own age and application conditions. The name marjoram is not enough to make all products equivalent.
03 · EXAMINE THE EVIDENCE
What the research shows.
A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.
A cell experiment is not an anticancer indication
- Type of research
- In vitro research described in the EMA report.
- Preparation concerned
- Infusion of leaves and flowers, subsequently freeze-dried, tested on cell lines.
- Observed results
- Growth inhibition was observed in the PC3 prostate cell line, but not in the HT29 colon cell line in the cited experiment.
- Limitations to consider
- Isolated cells, experimental concentrations and a growth effect demonstrate neither efficacy nor safety in a patient.
What can we take from this?
Cellular results are presented to explain the limitations of research, without proposing cancer treatment or anti-aging promises. An essential oil is not the aqueous extract studied.
