Pretty easy to grow your own, from seed even, but most plant nurseries will have these in their herb section.

- Aardwolf 5y agoAny risk of getting those elements in them if you grow them yourself, through the soil, water, fertilizer, products or the seeds?
- the-pigeon 5y agoAbsolutely. To be really certain you'd have to test your soil. I don't think you could test seeds without destroying them. But if your soil was clean then you could grow a plant from potentially contaminated seeds and that plants seeds would be far less contaminated.
- dylan604 5y agowhat about hydroponics
- robbedpeter 5y agoProbably the only reasonable way of guaranteeing clean plant food sources is to use hydroponics, and to manufacture fertilizer yourself. Distilling water is easy, and buying the chemicals for fertilizer seems doable. But you'll want to make your own hdpe containers, and silicone tubing, so you don't get unlisted phthalates or plasticizer. GRAS and "food safe" classifications are fine, for things that are actually looked for, but mistakes are made, and most failures seem to favor producers, not consumers. The question boils down to the actual harms you're mitigating and what constitutes the appropriate response.

- dsizzle 5y agoIt's not clear where the heavy metals are coming from. One possibility mentioned in the article is the soil itself. I wonder if even potting soil is tested for heavy metals? If heavy metals get through whatever food testing is done by the FDA, McCormick, etc., I don't have great confidence that soil testing is any better. That said, I would think growing your own is safer.
- NikolaeVarius 5y agoYou assume the soil you have is "safe"
- dsizzle 5y agoJust did a little searching and came across this https://www.latimes.com/archives/la-xpm-2009-nov-07-hm-realist7-story.html https://www.latimes.com/archives/la-xpm-2009-nov-07-hm-reali... That person did some lab testing and found high levels of lead in their backyard-grown chard.

- dsizzle 5y agoRight, there you go. (Although it doesn't say it completely ignores it either, just that it's not a focus.)
- _dark_matter_ 5y agoI wonder if hydroponically grown herbs would lack them. Could be a business opportunity, if people care enough (or the government steps in to regulate).
- windex 5y agoThe reason for these is probabaly the extreme depths from which water is pumped. The normal shallow ground waters arent this bad with arsenic I would assume.
