Theta (θ) Centaurus, Menkent, is the third biggest star in the constellation Centaurus, a double and variable, 2.2 to 2.7 and 14.3, red and bluish star in the left shoulder of the Centaur.

The name Menkent appears to be derived from the Arabic word mankib (“shoulder”) and Kentaurus, the Latinized version of the Arabic word for “centaur”. [source

The astrological influences of the constellation Centaurus

According to Ptolemy the stars in the human part of the figure are of the nature of Venus and Mercury, and the bright stars in the horse’s part of Venus and Jupiter. It is said to give hard-heartedness, inclination to vengeance, love of arms, strong passion, and an energetic nature. It may be connected with poisons. [Robson, p.37.]

The astrological influences of the constellation Centaurus given by Manilius:

"The Centaur, from his own nature assigns qualities to his progeny. Such a one will either urge on asses with the goad and yoke together quadrupeds of mixed stock or will ride aloft in a chariot; else he will saddle horses with a fighter or drive them into the fight [translator’s note; he will load horses with arms or drive them into arms, that is yoked to war-chariots].  

"Another knows how to apply the arts of healing to the limbs of animals [translator’s note; these endowments reflect the identification of Centaurus as Chiron] and to relieve the dumb creatures of the disorders they cannot describe for his hearing.

"His is indeed a calling of skill, not to wait for the cries of pain, but recognize betimes a sick body not yet conscious of its sickness". [Astronomica, Manilius, 1st century A.D, book 5, p.329].
