There is literature in which the assignment of plants to the various planets and signs of the zodiac can be read. These assignments are based, among other things, also on the morphological criteria and are not always conclusive when they are transferred from the whole plant 1:1 to the essential oil.


Herbs produce different active ingredients and compositions of active ingredients depending on their location and climatic conditions. When these plants are distilled, the resulting essential oils vary greatly in fragrance and application. These variations are labeled on the essential oil vial as “chemotypes.” The plant name alone would not be sufficient to identify which uses and precautions to take, since we are talking about the same plant species (and not a different variety). For example, we distinguish a

mild Thymus vulgaris, which has no known undesirable side effects in the aromatherapeutic context = chemotype linalool, thujanol or geraniol and   

pungent Thymus vulgaris, the use of which in an aromatherapeutic context in asthma, respiratory diseases, direct application to the skin or mucous membranes, during pregnancy and in infants and children requires caution = chemotype thymol or carvacrol.  

It is therefore obvious that these two chemotypes not only have different areas of application in aroma care or aromatherapy, but also embody different principles when used holistically.

Alchemy & Astrology

Alchemy (the study of substance properties and their reactions) is understood as an ancient branch of natural philosophy and is conceptually separated from modern chemistry or pharmacology (cf. Hübner). The distillation and extraction processes were originally alchemical separation processes for the extraction of certain substances. Even today, these production methods are common in modern pharmacy and agriculture.

The alchemists from past times also often involved astrology. Much knowledge from this field has been lost, deliberately destroyed or refuted over the centuries.

Magical Astrology & Fascination of the Ethereal

In our scientifically oriented world, people are again increasingly longing for traditionally produced products and applications (e.g. Demeter cultivation), even if they cannot, only partially or not yet at all be proven with contemporary research methods.

It is perhaps the magic of the intangible or incomprehensible (to which the “ethereal” = “volatile” belongs) that exerts this fascination on us humans, so that in recent times the demand for these things is increasing again.

In the Duden the meanings of the word “ethereal” can be read and are translated as: heavenly, (gossamer) delicate and spiritualized (cf. Duden).

Depending on the author and interpretation, the assignments of plants to planetary qualities do not always agree. Thus, there will also be different views and arguments that question the assignments we have created. Nevertheless, we have combined the know-how and experience of 20 years of professional astrology and aromatherapy to arrive at these results.

Biochemistry meets Astrology

For the first time, the biochemical mode of action of the volatile active substances of essential oils was contrasted with the qualities of the planets and signs of the zodiac. It was tried to find and show similarities between groups of substances and planets or signs of the zodiac. The active substances indicated in each case are to act supportively for the respective sign, if it is not sufficiently lived.
