This is an incredibly misleading click-baity headline. It's not turmeric that's killing people. Unscrupulous Indian manufacturers are adding lead to turmeric as a coloring agent, and that is what is killing people.
Note to downvoters: at the time I wrote the above comment the headline did not contain the word "adulterated", and the original headline still doesn't. It just says "How to stop turmeric from killing people."
