Tumeric - Curcuma longa

I used this picture even though it’s still in the bag because you can still see the turmeric rhizome sticking up. Now that it’s been in the ground for about a year, I can’t see any rhizome.
Turmeric (and annatto) are the two most common natural food dyes.
Medicinally, it is often regarded as a powerful anti-inflammatory although I have heard that this is mostly suppositional due to induction of Indian population as opposed to scientific studies?
