If we have children, we always air when they are away, and ventilate the rooms afterwards. If the house contains teenagers and adults only, you can strip the window openings before or after the windows are widened, observing the usual precautions (in particular a short period of spreading). Thus, we never heat essential oils on a vaporizer, which degrades them and can release toxic and polluting compounds: unlike what we’re trying to get!

Pro tip:

We prefer to use a cold or soft heat diffuser (there are different models on the market, at all prices).

How many drops, for how long?

We count no more than ten drops of the chosen oil (or a mixture of several of them), and spread for a maximum of 10 to 15 minutes.

Pro tip:

It is recommended to use an electric splitter with an automatic timer to avoid extra work.

In this case to avoid?

We avoid spreading with:

Children under 3 years of age, all people with asthma and epilepsy (or have a previous history), as well as pregnant and breastfeeding women.

Pro tip:

Before starting, we systematically check that the spread is not contraindicated (in general, the package or instructions should be kept) and, at the slightest suspicion, seek advice from our pharmacist … or choose another essential oil.! The ideal is always to rely on his Latin name, which avoids any confusion.

Our 7 best oils for cleansing the inside

Melaleuca alternifolia

Tea tree or tea tree (Melaleuca alternifolia)

It is better to purify the air of the house during periods of epidemic, because this oil extracted from the leaves of an Australian tree is a powerful antiseptic, antibacterial, antiviral, and, moreover, it has stimulating properties against microbes.


Its smell is strong but can be reduced by mixing it with an essential oil of eucalyptus, thyme or fir.


Citrus and lemon – Source: spm

yellow lemon (lime)

The fresh citrus aroma provided by this essence (obtained by pressing cold peels) covers unpleasant odors – it is ideal for the kitchen, bathroom and toilet. Purifying and antiviral, it also puts you in a good mood: ideal if your spirits are low and your nose is low at the same time!


None when used in broadcasts.


Nyaoli – Source: spm

Niauli (Melaleuca quinquenervia or viridifolia)

Extracted from the leaves of a tree in New Caledonia, it is highly antiviral and antibacterial, this eucalyptus cousin is preferred when the family is affected by any respiratory virus (cold, cough, sinusitis, etc.). As a bonus, it is an expectorant and boosts your natural defences.


It is contraindicated in case of present or past hormone-dependent diseases (especially female cancers).

Cinnamon camphor

Raventsara (Cinnamomum camphora cinoleverum)

It’s a winter staple, and an excellent anti-influenza that smells fresh and sweet! Derived from the leaves of the eucalyptus tree, it fights viruses, cleanses the nasal and pulmonary passages, purifies the air, and as a bonus, it even fights the fatigue that attacks us.


If their names are the same, do not confuse them with ravensara (Ravensara aromatica), which does not have the same indications: read labels carefully!


Rosemary – Source: spm

Rosemary cineole (Rosmarinus officinalis cineoliferum)

Well known in the kitchen, this fragrance is a valuable ally for all bronchial and respiratory ailments thanks to its anti-infective and anti-inflammatory properties. It is also recommended to use rosemary essential oil during the flu, it is tonic and fights fatigue: its dynamic aroma gives an instant boost.


Other rosemary (“medicinal eucalyptus” and “with Verbinone”) should not be crumbled.


Thyme – Source: spm

Thyme linalolife (Thymus vulgaris linaloliferum)

This powerful essential oil is one of our main natural allies in winter, especially for the prevention of respiratory diseases thanks to its antiseptic, antibacterial and anti-infective properties.


It can be replaced with thymus thujanol (Thymus vulgaris thujanoliferum), whose indications are similar, or ‘borneol’ or ‘saturated’ thyme (Thymus satureoides), which is less strong but milder (which we prefer to mix with other essential oils).

Siberian fir

Siberian fir (Abies sibirica)

So fun as it takes you straight into the woods (with a real Christmas tree atmosphere), this needlepoint essential oil perfectly cleans the air, decongests the respiratory tract, relieves coughs and loosens mucus: ideal if the whole family is “crowded”.


It is never used directly on the skin (but it is diluted in vegetable oil in equal parts). Always prefer to stream.

With these oils, do not spread

Some essential oils, although they smell delicious, should not be diffused in the air. This is particularly the case with cinnamon, which attacks the respiratory system. Rosemary “eucalyptus” or “medical verbenone” (on the other hand, rosemary can be propagated) is also prohibited. As for sour lavender, which contains camphor, it is strictly prohibited for patients with asthma and epilepsy because it can cause convulsions (however, there is no problem with lavender, real lavandin or lavandin, which are used more as an anti-stress). Finally, be careful with Scots pine, it is excellent for bronchoconstriction through the skin (diluted) but potentially an irritant through the respiratory tract: it should be diffused only in small quantities (one drop), and mixed systematically with other essential oils.
