If Saturn is weaker in strength, badly placed and not favouring the individual and delivering ill effects, then the individual is advised to wear this root of Bichuwa also known as Tephrosia purpurea.
After getting the root or jadi of ‘Bichuwa’ also known as Martynia annua o Saturday purify it with Ganga Jal and do puja by offering dhoop, deep, flowers and chanting mantra of Saturn (shani). Then wrap it in black or blue cloth or thread and tie it to the right arm in evening.
Alternatively, you can also do the above puja during any of the Constellations / Nakshatras of Saturn – Pushya, Anuradha and Uttarbhadrapad.
Mantra: “Aum Praam Preem Proum Sah Shanishchraya Namah”
Alternatively you can also use “Dhature ki root or Jadi” also known as Datura stramonium for Saturn.
