The perfumes apply specifically to the twelve zodiacal signs rather than other correlations associated within popular astrology. If you are a Pisces, thyme is enough.

As for whether thyme will help during moon transits, the best way to overcome negative lunar influences is to meditate and eliminate the lunar ego, so as to no longer be subject to mechanical laws.

Some illnesses or symptoms can be alleviated through the zodiacal perfumes, since our current zodiac predominates in relation to our personality, temperament, and body in this lifetime.

By strengthening the positive elements of our zodiac through its correspondent perfume, we provide an atmosphere (at home) to cultivate such superior influences rather than the negative (relating to, perhaps, some dissonant, traumatized, or negative elements of our personality).

If you want to work with the energies of a planet, utilize the following perfumes and invocations:
