Valerian

Valerian (Valeriana officinalis): A Sacred Symphony of Calm

Esoteric Profile and Planetary Correspondences

Valerian is a plant ruled by Mercury in its aspect of deep immersion into the subconscious, and it is under the patronage of the Moon, whose cold and moist emanations it embodies. In the spagyric tradition, valerian is considered a "key to silence," capable of harmonizing chaotic mental currents. Its root, carrying a heavy, earthy energy, serves as an anchor for a spirit in a state of agitation (affect). In the alchemical process, valerian is used to separate the "volatile from the fixed": it helps extract the essence of tranquility from psychic noise.

Biochemical Structure and Mechanisms of Action

From a biochemical perspective, valerian is a complex of synergistic compounds that act on the GABAergic system:

• Valepotriates (iridoid glycosides): These are key psychoactive components. They possess sedative and anxiolytic effects, influencing the permeability of neuronal cell membranes.
• Valeric and isovaleric acids: Breakdown products of valepotriates that inhibit the enzyme GABA-transaminase, preventing the degradation of gamma-aminobutyric acid. This prolongs inhibitory processes in the central nervous system.
• Essential oil (borneol, pinene, camphene): Provides an antispasmodic effect on smooth muscle, relieving visceral tension caused by psychosomatic factors.
• Alkaloids (valerine, chatinine): Act as mild modulators of neurotransmission, promoting the synchronization of brain biorhythms.

Spagyric Application

In spagyrics, valerian undergoes fermentation and subsequent distillation to extract the Spiritus (spirit), Sulphur (soul/oil), and Sal (salt/mineral residue).

• Tinctura: An alcoholic extract obtained by macerating roots harvested during the waning Moon, it acts as a "mirror," reflecting internal anxiety and returning it to a center of rest.
• Essence: Prepared by calcining the roots to ash (Sal) and subsequently reintegrating them with purified alcohol, it is used in alchemical medicine to treat "diseases of the spirit" manifesting as insomnia, tachycardia, and nervous exhaustion.

Biochemical Influence on the Body

Valerian acts as a mild modulator without causing cognitive dulling. Its primary task is the normalization of the excitability threshold of neural networks. The biochemical response consists of increasing the concentration of GABA in the synaptic cleft, which shifts the body from a state of sympathetic dominance ("fight or flight") to a state of parasympathetic relaxation. This makes it an indispensable tool for the alchemist seeking to achieve a state of Anima Tranquilla—the calm soul necessary for deep meditation and laboratory work.
