Ancient Sunrise® Purity Henna batch #101509 is certified by Alkemists Pharmaceuticals to have 2.3% lawsone content, 0% pesticides, no contaminants, and no additives. When you buy henna from mehandi.com, you  know for certain what the dye content is, and what the pesticide and lead levels are.

The sift is very creamy and not prone to cracking or clogging, even in the finest applications.  The dark areas in the picture above were dark ruby 8 hours after paste removal and peaked at raven's wing black 36 hours after paste removal, following an overnight application.  The lighter toned areas were the result of a four minute application.
