There is a ritual called Sri Choorna Pratishta. Sri Chooronam is prepared with turmeric in households, then recite mantras like Sri Suktam, and consecrate (Pratishta) it just like they consecrate the Deity (Perumal). Vedic scholars adorn this. One should not wear that consecrated Sri Chooronam during the period of asaucam (Theettu). Nowadays, this practice is not prevalent in most places.
