Turmeric is often adulterated with cheap ingredients (one of which might be LEAD, for crying out loud!). I used to think I was up on what is toxic and what is not, but totally missed this one until recently. I use turmeric a lot — it’s not just an infrequent seasoning to me — I occasionally take it in a fairly high dose (500mg – 1g) as a supplement, and sometimes as an anti-inflammatory. I’m not telling you to do that. This is not medical advice. I’m just saying… I use a LOT of turmeric!
So, guess what? There are some ways you can test your turmeric at home to see if it’s been adulterated! One of those ways is the water test There are many articles and videos — google it, you’ll see. For your convenience, here is one looks like it is from the Ministry of Health & Family Welfare of India. I can’t vouch for the accuracy of this information, but I have seen this test listed in a variety of places, many of which seemed legit. But keep your skeptic pants on and do your research into the validity of this if you’re going to take action on it.
I tried it myself, with the four types of turmeric I currently have in my house, and I was shocked at the difference! I cropped the photo close, so that you can’t see my labels, because I don’t want to disparage anyone, especially since this is very unscientific. But check out my results!

According to the test, it seems like the one on the left is the best one, and if this test is really a way to tell if turmeric is adulterated, it certainly looks like the one on the right meets that criteria. (I put the turmeric in the water left to right, so the one on the left actually had the turmeric in it the longest.)
Though I won’t give out actual brands/names on this, I will tell you the source types for each. From left to right:
- A turmeric/curcumin supplement (I opened the capsule)
- Small, family farm (US-based)
- US-based company that sells turmeric in bulk packages.
- Small, family farm (international)
Now, I need to find a source for concentrated hydrochloric acid, to do more of these tests! And from now on, it will only be third-party lab-verified turmeric for me! I don’t care if it costs more!
