Tuesday is ruled by the planet Mercury which is the ruler of Gemini [3th house] and Virgo [6th house] , the 6th house has to do with Health , and Mercury was recognized and remembered across time as a 'healing' planet due to it's energies/properties and many other complicated stuff.
So that is why , it also depends of what you want to heal/release yourself from precisely , If it would be for whatever reasons then one should check the ' Diseases/health ' section under the planet details , for instance at Mercury this deals with: "The brain, the cerebrum-spinal system, the senses of sight, hearing, taste, the organs of speech, the reflexes, and the hands. Nervous disorders, speech disorders, asthma, tremors, tuberculosis and other diseases of the lungs." so if one has any of those then best time to chose for such a working would be in a Tuesday at Mercury hours even or the Sun.
But regardless of how 'specific' some energies are of those planets , they all do work and manifest health and many other things into reality , they are what would many call ' miraculous ' , planetary squares are if not maybe the strongest things one could do and handle.
Put it this way , what one is able to handle for somebody else that one day of the energy you accumulate [ meditation ] would literally destroy the other one, big times , like if a novice does let's say a crazy amount of vibrations of a strong mantra + a lot of other suprasolicitations [ but warnings are there for that ].
