If Jupiter 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 Banana or piece of Turmeric (Haldi).
To get rid of the inauspicious results of Brihaspati (Jupiter) after getting the root of jadi of banana or a piece of Haldi (Turmeric) purify it with Ganga Jal and facing north direction on Thursday, offer puja with Dhoop, Deep and flowers chanting Jupiter mantra. Then wrap it in yellow colour cotton piece of cloth and tie it to the right arm.
Alternatively, you can also perform above puja during any of the Jupiter constellation/ Nakshatras- Punarvasu, Vishakha and Purvabhadrapad Or on any Poornima day.
Mantra: “Aum Graam Greem Groum Sah Brihaspataye Namah”
Alternatively you can also use root of “Bharangi” also known as Pygmaeopremna herbacea for Jupiter.
