Dr. Berkowsky’s Synthesis Materia Medica Spiritualis of Essential Oils is the central reference text for Spiritual PhytoEssencing™ in which each of the essential oils are profiled with respect to their inner soul-nature. He utilizes knowledge from a number of different modalities and schools of thought to base his information on including: Historical Use and Folklore; Herbal; Aromatherapy; Anthroposophy; Traditional Chinese Medicine; Homeopathy and the Jewish Kabbalah. His information is further based on the homeopathic concept of Miasms; the Anthroposophical concepts of the Three Fold Organism and Constitutional Elements of humans and the Kabbalah Tree of Life and its 10 Sefirot.

I thought it might be interesting to write periodical blogs concentrating on an individual Sefirah and the essential oils associated with it.

The first and most exalted of the Sefirot is Keter (Crown). On Adam Kadmon, it is visualized as being just above the head. It can be thought of as the Sefirah through which the light of all creation continuously flows. It is unapproachable, unknowable, impossible to grasp, it is the emanation that enables the Tree of Life, and therefore the world, to exist.

We can only know Keter by what it represents, which is constant creation. It relates to God’s description of Himself in the Hebrew Bible as an ever-present creative force of continuous becoming, expressed in the words “I Will Be That Which I Will Be”. Keter demands from each of us that we be fully alive in order to be ready to receive God’s teaching with wisdom (Chokma) and to act with understanding (Binah).

Keter is the primeval root of all reality, the highest spiritual core. At times Keter is referred to as the ‘will of all wills’. It is frequently called Ratzon (Will) by Kabbalists themselves.

Keter is associated with the planet of Neptune and the astrological sign of Pieces (Feb 20 – March 20), as well as Metatron, often considered the King of Angels.

Three essential oils associated with the Keter are Cedarwood, Coriander and Rosemary.  There are others but these are the three I will highlight today.


Psychologically, cedarwood’s calming, sedative properties have been found to be helpful for stress, tension, nervous disorders, fear and anger.  On a physiological level, cedarwood is used for many conditions including bronchitis, cough, arthritis and cystitis.  It is often used as an insect repellent.  On a subtle level, Cedarwood helps us to get back in touch with our true reality by affirming and clarifying our focus.  It is grounding.  Cedarwood can be used to clear and cleanse a room of negativity and bring in positive energy.  It clears and steadies the mind and promotes a calm meditative state to better receive healing energy.  It strengthens the connection with the Divine.  It helps one to maintain a sense of balance and control in life.  Cedarwood enhances spirituality.  Cedarwood enhances stability, integrity and solidarity in all things.
Cautions: Avoid during pregnancy.

Spiritual PhytoEssencing Themes  The themes of faith, will, strength and security run strongly through Cedarwood.



Psychologically, coriander is helpful for migraine, neuralgia, nervous exhaustion and insomnia, while on a physiological level it has been used for colds and flu, digestive complaints, muscular aches and pains and arthritis. On a subtle level, Coriander can help promote feelings of security.  It may increase creativity, spontaneity and passion, as well as promote confidence and motivation.  It is considered to be an aid to improving memory.  It is useful to use coriander to assist recovery from illness, both physical and emotional.  It may be helpful at times when one is depressed or unsure of one’s ability to heal.  Coriander is used for healing and love potions.  Coriander is a gentle and compassionate oil.
Caution: Generally considered non-toxic, non-irritant and non-sensitizing.

Spiritual PhytoEssencing Themes:The major theme found in coriander is the strengthening of spiritual faith in those who have experienced a great deal of stress and travail.



Psychologically, Rosemary has stimulating properties.  It is an excellent oil to consider when there is physical exhaustion, feeling rundown, headaches, migraines, mental fatigue and nervous exhaustion.   It is excellent to use in the mornings when one needs a bit of help in getting going.  Probably best to avoid its use at night, as it might prove too stimulating and make it difficult to sleep.  It is also excellent for memory.  On the physiological level Rosemary has analgesic, anti-inflammatory, antispasmodic, antiviral, expectorant and mucolytic properties.  It is said to strengthen and promote hair growth.  It can be useful for many respiratory conditions as well as muscular aches and pains, cramps and spasms.  It is also considered to be helpful in cases of gout.  As an oil from a culinary herb it is useful when suffering from upset stomachs, flatulence and constipation. On a subtle level, Rosemary can be used for loyalty and love.  It can comfort emotional heartbreak, and may be appropriately used to help achieve closure to a relationship.  It can be used in any grief blend.  Rosemary clears and cleanses a room.  It helps provide protection from negative influences.  It aids in helping to establish healthy boundaries in relationship.  It can promote self-confidence and strengthen will power.  It can inspire joyful love.  It clears the mind and enhances memory.  It can provide psychic protection.  It inspires faith and helps one to remember one’s spiritual path.  Rosemary helps to promote clear thought, clear sight or vision and to develop clairvoyance.  It is often used in love and healing magical blends.
Cautions:  Generally considered non-toxic, non-irritating and non-sensitizing. As it is highly stimulating do not use when you need to sleep.  Use with caution with epilepsy, high blood pressure and pregnancy.  Both the chemotype verbonone and chemotype camphor should be avoided with small children and during pregnancy due to their high ketone content.

Spritual PhytoEssencing Themes: The interlocking themes of oneness, memory and faithfulness are fundamental in rosemary.
