Hi, Kali haldi will have black stripes on leaves.and when the haldi is cut it will be in inkfaded blue colour. how to test this product. if it is really functional it can break open a 6 lever godrej lock within 15 min of time and the lock will be hot. there is also a needle bend test. as per our shasthras this herb has got the power of kali matha. it is very auspicious but at the same time risky too.

cheers,
