Sorry to hear
I found that most times when leaving saffron on top of a half full cup of boiled milk and then mixing it a while later, the milk would still retain most of its white colour. One day I poured the warm milk in a bottle and sprinkled some saffron inside. After 15 minutes and shaking the bottle every 5 minutes, the milk became a stronger yellow colour than its normal white with yellow tinge and the next day was noticeably quieter.
Its harder to get the saffron out of a bottle as it starts to foam after shaking it and the saffron threads stick to the bottom of the bottle. I now crush saffron strands inside my cup with a tea spoon before pouring warm milk (not the most efficient was of crushing). After mixing, the milk turns to a banana yellow colour which I believe increases it's potency.
Some days T is louder than others. Studies have show that saffron should be taken for 8 or so weeks so I will continue to take it for the time being.
