The Ancient Herbalists Assigned Herbs to Planetary Rulers

Why the Ancient Herbalists Assigned Herbs to Astrological Rulers

As far as we know, there are no more planets in this Solar System that have plants growing on them, though some people have suggested there may be vegetation of some sort on Mars. Ancient herbalists, however, had a system of assigning herbs to planetary rulers; in other words, they claimed that deities linked with the heavenly bodies held dominion over herbs that grow on Earth. Let us take a look at a selection of herbs that were placed under the astrological ruling of other planets, and see why it might have been that herbalists, like Culpeper, decided to assign them to specific heavenly rulers.

Herbs of Mars

Nicholas Culpeper was one of the most famous herbalists who believed that medicinal and culinary plants could be grouped in this way, according to their various characteristics that were linked to those of a specific god or goddess. For example, because Mars was regarded as the god of war, herbs that had something aggressive about their physical appearance or something that resembled blood, were candidates for being ruled by this planet. The strange Dragon Tree (Dracaena draco) is a perfect example of a herb ruled by Mars because it has sword-shaped leaves, reddish-coloured berries and it bleeds a resinous sap that goes a dark red when dry and is known as dragon’s blood. The Dragon Tree comes from the Canary Islands, and a specimen in the town of Icod de los Vinos is thought to be 1,000-years-old or more. It is known as the "Drago Milenario," has its own park, and is a tourist attraction nowadays.

Herbs of the Sun

Herbs of the Sun include the Sunflower (Helianthus annuus) and the Chamomile (Anthemis nobilis). These two plants have petals that radiate out from a central disk like the rays of the Sun, and the Sunflower is, of course, a bright yellow, which is a colour linked with the central star of our Solar System. The St John’s Wort (Hypericum perforatum) is another herb in this group. It has yellow star-shaped flowers and is harvested in midsummer when the Sun is at its strongest and the days are at their longest. St John’s Wort has become well-known as a herbal antidepressant, and one of its alternative names is Sunshine Herb. Mistletoe (Viscum album) is an herb of the Sun because it was traditionally harvested by Druids at the time of the Winter Solstice. It was cut down from an oak tree using a golden sickle.

Herbs of the Moon

Herbs ruled by the Moon were often ones that are associated with water, because the Moon is linked with the oceans because it causes the tides. White flowers or a silvery colour on the foliage are other characteristics linked with the Moon, and plants that have something to do with the night might also be thought of as herbs of the Moon. The White Water Lily (Nymphaea alba) is a herb ruled by the Moon. This is because of its white flowers, rounded leaves, like full Moons, and because it grows in lakes and ponds. The Jasmine (Jasminum officinale) has white blooms and its perfume is strongest at night. The White Willow (Salix alba) is another herb under the dominion of the Moon. Willows, of course, like to grow by water. The Lettuce species (Lactuca spp.) are ruled by the Moon too. This is because they have a white milky sap if cut. This sap is known as "Lettuce opium" and has similar sedative effects.

Herbs of Mercury

Mercury was thought of as the messenger of the gods, so herbs ruled by this planet have to really communicate to us in some way. Strongly aromatic herbs were often chosen as herbs of Mercury. The Fennel (Foeniculum vulgare) is a great example of a herb in this group. It communicates to our senses with the visual appeal of its tall graceful stems and ferny foliage, to our tastes with its sweet and spicy flavour like aniseed, and with its scent like anise when crushed. It is used both as a culinary herb and in herbal medicine.

Herbs of Venus

Herbs ruled by Venus, not surprisingly include the Rose, which is a symbol of love and passion, and, of course, Venus is the Goddess of Love. The pretty blue-flowered Periwinkle (Vinca spp.) is another herb in this group, and this is because it has been used in love potions and spells. It was thought that merely sprinkling this herb under the bed of a couple of lovers would increase their passion. In fact, the Periwinkle is a poisonous plant but that never stopped it being linked with love.

Herbs of Jupiter

Jupiter is a giant planet and expansion is one of the characteristics associated with it as a planetary ruler. Various trees come under its dominion because of their spreading branches. One of them is the Lime Tree (Tilia spp.), a tree which gives us lime flower tea, which is known to help relaxation and is very popular in many parts of Europe. It was once thought that anyone suffering from epilepsy would be healed by merely sitting under a Lime's branches. The Oak (Quercus) is a very important and sacred tree for Druids, and it too comes under the rulership of Jupiter.

Herbs of Saturn

Saturn is another gigantic planet and famous for its rings. To the Ancient Herbalists it was associated with the passing of time and with old age and death. It symbolises the “Grim Reaper.” Many poisonous herbs come under its dominion. The Deadly Nightshade (Atropa belladonna), the Henbane (Hyoscyamus niger), Hemlock (Conium maculatum) and Monkshood (Aconitum napellus) are all very dangerous herbs that were once used by witches as ingredients for their “flying ointments.” The Morning Glory (Ipomoea violacea) is another herb under the dominion of Saturn. Its flower has a circular mouth to a funnel-shape and could remind us of the Rings of Saturn. Its seeds, especially in varieties like "Heavenly Blue," contain lysergic acid amide, which as hallucinogenic effects and has often been used by hippies and shamans because of this. This flower looks so beautiful it could be from another world, and its psychoactive effects could make you feel like you were on one.

In Conclusion

Thinking about how the herbalists assigned various herbs to the rulership of planetary deities, according to their characteristics, certainly makes for a fascinating study and something for us to think about. My new book Herbs of the Sun, Moon and Planets (Moon Books) explores this subject in greater detail.
