When we understand the similarities as well as the differences, between Clove Bud CO2 and Clove Bud essential we are able to choose the best aromatic for our formula.

Common to both

Name: Clove Bud (Syzygium aromatica)

Family:   Myrtaceae

Plant Description:  A slender evergreen tree with a smooth, trunk that grows up to 12 meters high.  It has large bright green leaves.  At the start of the rainy season, long buds appear with a rosy-pink corolla at the time; as the corolla fades, the calyx slowly turns deep red.  The calyxes are beaten from the tree and when dried are the clove buds.

History/Folklore:  One of the first recorded uses of Clove Bud was recorded in the Chinese Han period 220 – 206 BC where it was used to sweeten the breath.  Cloves were introduced into Europe in the 13th Century. Cloves were once one of the most prized of all commodities and the early history of the clove trade is characterized by deceit, covetousness and violence.

Emotional and Spiritual Conditions

Both the CO2 extract and the essential oil have analgesic, antispasmodic and stimulating properties and would be helpful for dealing with headaches and fatigue.  Their stimulating properties help to stimulate the mind and help promote memory.  On a subtle level, Clove Bud encourages introspection into pain.  By helping one to reflect on the root cause of fear, pain and anger it allows one to move forward into greater joy and spontaneity.  In Dr. Bruce Berkowsky’s Spiritual PhytoEssencing, chronic nervousness and anxiousness are considered to be important factors in the Clove individual.
