Top 14 Critical Essential oil Precautions, their Storage, Use, and Oils to Avoid

Updated: May 8, 2021

Nature is mysterious!

She has her reasons for creating things the way they are.. Botanists, zoologists, geologists have barely scratched the realms of her reason.

Something natural, may not always be safe.

Thousands of plants/herbs are born with varying levels of natural toxicity.

One must exercise caution, especially when it comes to choosing and using Essential oils.

Consider these facts about Essential Oils:

1. Essential oils are produced by plants to secure themselves from natural dangers. Oil-rich plant parts like bark, seeds, leaves, flowers, are usually the ones, at receiving end of natural threats.

2. An Essential oil may have anything between 1 to 1000, different chemical compounds, with multiple biological activities.

3. Essential oil molecules are tiny but a single drop can contain about 40 million trillion molecules.

Imagine that! .... Even a single drop could be too much for the ‘meager’ 30 trillion cells in the human body.

It just takes one molecule of the correct essential oil to hit the limbic system(brain) and jumpstart the process of influencing the cells, bloodstream, and organs to deliver its benefits to the body and emotions.

Too many, simply freeze the system and sometimes lash back with a reaction.

4. Essential oils are highly concentrated:

a. It takes about 1.35 kgs lavender flowers to just make 15ml lavender essential oil

b. It takes about 2.42lac rose petals to make just 5 ml rose essential oil

So, one can imagine how much of a punch is packed in a single potent aromatic molecule. Even a perfectly safe essential oil can deal a toxic blow if:

· Used neat (non-diluted)

· Used daily or too frequently

· Used intermittently but in large doses.

· Used by vulnerable groups such as infants, children, pregnant women, or even the elderly.

· Used on delicate body parts such as eyes, ears.

The Top 13 Critical Essential Oil Precautions;

Their Storage, Usage, and Oils to Avoid:

1. Less is more with Essential oils:

Essential oils are highly concentrated and hence prone to causing irritation. It just takes a molecule of a drop to work its therapy. More can cause, allergies and rashes and unwanted reactions

2. Never use Essential oils undiluted.

Mix them with organic nourishing oils like Jojoba, Argan, Sweet almond, Virgin Coconut oils, etc.

The Essential oils will bond with the fats in the carrier oils, and thus get beneficially delayed in their absorption by the fats in the skin.

This reduces the risk of skin irritation.

3. Avoid using the same blends daily/a prolonged time.

This can also cause adverse reactions.

Luckily, many oils fall in homogenous groups with similar properties so one can keep switching within the same group.

4. Buy only therapeutic grade oils, watch out for adulteration.

Check labels that say ‘therapeutic grade’.

The manufacturing and selling of essential oils are not highly regulated so marketers slap labels that work for them.

A wiser choice would be to opt for reputed large players.

· Do not confuse fragrance oils (commonly called aroma oils) for essential oils. They are synthetic, often with a stronger scent, and will have zero therapeutic properties on skin or health.

· Check for ingredients, whether it is blended with vegetable oil or cheaper versions of the same essential oil or only 100% Pure essential oil

· Check for the distillation method used. Solvent extraction often produces oils of lower quality but is a cheap option for the company.

· Check for the region where the plants were cultivated. The region of origin will have a specific composition for each sub-species of plants, as the plants' defense system will differ from place to place.

· In the case of a blended oil bottle, do check the ratio of the blend. If it comprises of an expensive essential oil like Rose blended with a little cheaper one like Lavender, then check in what ratio are they blended. That could determine the right price.

· Cheap products could mean lower quality oils.

Following are the 4 grades of Essential oils:

Therapeutic Grade Oil

· Pure & Unadulterated

· Grade A essential oil

Natural/Food Grade Organic & Certified oils

· May have artificial chemicals

· Grade B essential oils

Perfume Grade Extended or altered oils

· Contain Chemicals & solvents

· Grade C oils

Floral Water

· Depending on the kind of organic raw materials, this can either be Grade A or of poor quality.

· Used in case of expensive oils like Rose Essential Oil

Check other factors that may not be mentioned on the label but can be considered as they impact the oil components:

· Storage, Rainfall, and Soil type

5. Consult a doctor before using any essential oil when you have a health condition

· A stimulating oil might be negative for epilepsy.

6. Do a patch test beforehand to check how the oil responds to your skin.

· For sensitive skin, the dilution rate has to be very low less than 0.5% for topical application. Meaning 0.5 ml essential oil to 100 ml carrier oil.

· Put a drop of diluted essential oil on the inside of your wrist, plaster it, and check for a reaction after two hours. If there is redness then apply almond oil and wash off immediately.

7. Storage Guidelines for Essential Oils

(Avoid degradation by oxygen, heat, and light)

· Store in a dark/amber glass bottle. Essential oils can eat through plastic.

· Store in a dark place. Exposed to light they can get destroyed

· Keep it in a cool place, preferably in the bottom of the fridge.

· Keep the lid tightly screwed on. Essential oils are volatile and can evaporate quickly.

· Never leave the bottle open for more than a few seconds as Essential oils will oxidize in the air and lose their therapeutic qualities.

· If the seal is missing in a bottle, dispose of it or replace the broken lid.

· Keep out of reach of pets or children.

· Keep out of reach of highly polished surfaces.

8. Flammability of Essential Oils

Many essential oils are flammable. Never keep the bottle close to a naked flame or near flammables or any source of ignition.

9. Shelf Life of Essential Oils

· When an essential oil is blended with a carrier oil, its shelf life is reduced and must be used within a few months. Stored right, a diluted blend can be used between 6 to 12 months.

· Carrier oils can also go rancid if not stored properly.

Eg Avocado oil has an extremely short shelf life.

· If there is a change in the scent or the texture, then it’s a sign that the oil has to be thrown out as it can cause irritation.

· Do not leave essential oils in the car in the summer.
