Mercury in Medical Astrology
In medical astrology, Mercury governs not only the nervous system, respiratory system, and the function of the hands and arms but also influences the thyroid gland’s health and functioning. The thyroid gland plays a crucial role in regulating metabolism, energy levels, and various bodily functions. Mercury’s influence extends to the intricate network of nerves throughout the body, facilitating communication between the brain and other organs. This includes the transmission of nerve signals responsible for sensory perception, motor coordination, and cognitive functions.
Moreover, Mercury’s association with communication extends to the exchange of information within the body, including neurotransmission and cellular signaling pathways. Imbalances or afflictions related to Mercury in the birth chart may manifest as a variety of health issues, including nervous system disorders such as anxiety disorders, nervousness, insomnia, or conditions affecting respiratory health like asthma, bronchitis, or respiratory infections.
Furthermore, Mercury’s rulership over the hands and arms implicates its influence on fine motor skills, dexterity, and manual coordination. Afflictions to Mercury may manifest as issues such as carpal tunnel syndrome, repetitive strain injuries, or conditions affecting the hands and arms’ mobility.
Understanding Mercury’s role in medical astrology can provide insights into potential health vulnerabilities and guide preventive measures or therapeutic approaches aimed at restoring balance and promoting overall well-being.

Mercury in World Religions

- Greek and Roman. In ancient Greek and Roman scholarship, Mercury was associated with the messenger god Hermes (Greek) or Mercury (Roman). Hermes/Mercury was considered the divine messenger for his speed and agility. He was often depicted with winged sandals and a winged helmet, symbolizing his swift movements and role as a messenger between the gods and mortals.
- Christianity. Mercury is not directly linked to Christian scholasticism. In the early centuries of Christianity, astrology was widely practiced in the Roman Empire and surrounding regions. However, the Catholic Church took more definitive actions against astrology during the High Middle Ages and the Renaissance.
- Hinduism: In Hindu mythology, the planet Mercury is associated with the god Budha (not to be confused with Gautama Buddha). Budha is considered one of the Navagrahas, or nine celestial deities, and is believed to govern intellect, communication, and commerce. In Hindu astrology, the position of Mercury in one’s birth chart is believed to influence various aspects of life, including intelligence, speech, and business acumen.

Buddhists emphasize the cultivation of wisdom and understanding, traits that align with the intellectual attributes associated with Mercury in astrology.

Mercury is often associated with the principle of communication, transformation, and the merging of opposites. The symbol of the caduceus, a staff entwined by two serpents and topped with wings, is often attributed to Mercury and represents healing, balance, and the integration of dualities.
- Astrology: In contemporary astrology, Mercury is associated with communication, intellect, adaptability, and the conscious mind. Its position in the birth chart is believed to influence one’s cognitive abilities, learning style, and modes of expression. Mercury retrograde periods, during which Mercury appears to move backward in its orbit from the perspective of Earth, are often associated with communication challenges, technological glitches, and misunderstandings.
- Kabbalah: In Kabbalistic tradition, the planet Mercury holds symbolic significance within the framework of the Tree of Life, a central symbol representing the mystical aspects of Jewish mysticism. Within the Tree of Life, Mercury is associated with the sephirah (emanation) called Hod, which represents intellect, communication, and the power of thought. Hod serves as a bridge between the divine and human consciousness, enabling individuals to access higher wisdom and spiritual insights through intellectual inquiry and reflection
