Oshadhi Usa - Quality Standards

Our brand name is synonomous with the highest degree of purity, the finest quality of scent, together with a rich diversity of products.

It is Oshadhi�s principle to choose producers not according to their greatest possible output, but on the basis of the purity and energy of their products.

Comprehensive analyses and quality controls, supported by on-going state-of-the-art laboratory tests, are prerequisites in the selection of our line. This includes tests such as:
  • Optical rotation
  • Density
  • Refranction
  • Gas chromatography analysis
And, if necessary, mass spectrography

Thus we distinguish between: c.org.: certified organic production (Ecocert)

No use of chemical fertilizers, pesticides, fungicides or herbicides. Slow water or stream distillation technologies are used to preserve a maximum of active ingredients and scent components; no overheating of the essential oils.

trad.: traditional cultivation

Similarly tl certified organic production. No use of chemical fertilizers, pesticides, fungicides, herbicides, and no overheating of the essential oils. However, they come with no certificate from public or private institutions such as Ecocert. Cultivation and distillation are done for the most part according to the standards of long-established family business.

wc.org.: wild-grown, certified organic

Identical to certified organic, except that the oils are derived from wild-grown plants.

wild: collection from wild plants These essential oils are derived from plants that are usually only found in natural habitats. For example, many conifers and eucalyptus varieties belong to this category.

sel.: selected

A variety of essential oils in this category come from countries where certified organic cultivation is not yet known. This does not mean that the plants used have necessarily been treated chemically. We also select these oils on the basis of our traditional standards of purity and scent quality. Some of these oils van be less expensive alternatives to certified organic oils from the same plant.

Purity and Quality of Essential Oil

As essential oils gain greater acceptance for their therapeutic value in daily life, a growing number of people are expressing concern about the purity and quality of the essential oils available on the market.

Until recently essential oils have primarily been used in industry for perfuming, detergents and for flavouring (aromatics). Their use as raw material for fragrancing and the need to reduce costs have compelled many manufacturers as well as exporters to dilute or adulterate essential oils.


The lack of reliable information regarding the origin and purity of essential oils leads to an uncertainty in the market. Many people, motivated by their research for alternative medicine and aromatherapy, are being introduced to essential oils for the first time. Some do not yet have the ability to determine quality. They usually buy their oils from the industry which often is not supplying fully natural, unadulterated products


In order to reduce expenses the perfume and cosmetic industry has synthesized a number of plant derivates.

Many of the chemical substances from petrochemical derivates only reproduce the fragrances, but not the medicinal effects found in natural essential oils.

Because they isolate only the chemically active ingredients of the plant, synthetic substances only produce a chemical effect.

But the pure essential oil is an expression of the whole plant and, as one would expect, produces a holistic effect.


Ideally, essential oils for therapeutic application should stem from chemical-free unpolluted areas of cultivation (certified organic, traditional, wild crafted plants).

We feel that this is the way true aromatherapy should be dealt with, so that the customer receives the optimum benefit from his choice. For the sake of transparency and in order to facilitate the identification and aromatherapeutic usage essential oils should be defined with regards to their
  • exact botanical name
  • country of origine
  • part of plant used for distillation
  • mode of cultivation
  • major compounds

Essential oils should not be denatured, adulterated or mixed as such with other oils.

The careful selection of suppliers, if possible through direct sourcing, and continued laboratory testing guarantees that essential oils are 100% pure.

A good aromatherapy company has no other choice than to build a close relationship with farmers in many countries who cultivate healing plants organically. As a result such company can offer an extensive resource of a rich variety of untreated essential oils.

Through personal contact with the farmers one knows that they practice methods of cultivation which are in accordance with the natural laws of the land and utilize methods of distillation which do not damage the pure essences from the plants.

6. For all therapeutical essential oils and synergies the following points are valid:

a) Distilled essential oils should ideally be derived by low or medium pressure steam distillation without use of chemical solvents.

b) All oils should be unadulterated 100% pure natural products - no chemical additives, diluting with alcohol or thinning with other oils should occur, unless necessary for certain purposes (i.e. access to the product because too solid, creation of new products...)

c) Essential oils should not be peroxidized, decolorized, nor deturpenated.

d) The chemical profile or "chemotype", of the essential oil's major active substances should be indicated, along with the plant part used for distillation, the cultivation method and the biological name.

e) Careful testing for purity using gas chromatography and - if necessary - mass spectrography should be practiced regularly.
