Chromium Spiked up from Toxic Holy Basil?

 My chromium just spiked up on my last test

Thought it might have been my brand new thinning shears (which work perfect for those with short hair)

But just stumbled on this article about Holy Basil  (also called Tulsi)

Most of the potential side-effects of tulsi are not acute effects but rather, long-term points of caution that might not be immediately apparent to casual herbal tea drinkers. The Ocimum tenuiflorumplant is able to grow in areas with a high concentration of chromium, which would normally harm most plants; because it tolerates high levels of chromium, it can accumulate the metal in its leaves to potentially toxic levels.

Chromium can damage the liver and kidneys. Tulsi grown in polluted areas is thus not safe for human consumption.[10] You can avoid this problem by buying organic tulsi and being familiar with the source of the herb, or by growing your own herb in soil that you are familiar with.

I took Holy Basil quite a bit from 2008 to 2013..... sigh. Sounds like it depends where it was grown.    We'll see if it goes back down the next test
