When choosing plants for a spell or amulet it can be very useful to take note of the planetary rulers of the plants or plant parts you are using.
To get the most potency from the planetary influence harvest your plant at the time when its ruling planet is in a position of strength.
However this is not always possible if that specific plant doesn’t grow in a location that is accessible to you.
This should not be a problem as each planet rules over a huge variety of herbs and plants so it should be quite simple to find an alternative
When deciding on what plant to use consider the appearance of the plant, whether you are using its leaves, fruit or roots and where it grows naturally.
Different parts of the plant have different rulerships and uses. Roots are thought to influence the brain, stems the bones, flowers the lower belly and genitals. Each part of the plant are also ruled by different planets:
Fruit – Jupiter
Flowers – Venus
Seeds or Bark – Mercury
Wood – Mars
Roots - Saturn
Leaves – Moon
The planetary ruler of the plant part being used is thought to be the secondary ruler. Most of the rulerships now used survive from lists written in the seventeenth century, and these lists were often simplified from earlier sources. If you want to study the subject of herb associations a good book to get is Culpeper’s Herbal, originally called The English Physician.
