Original research and synthesis
Information from the article I quote: "If ingested, lavender oil is poisonous in amounts as small as 5ml due to its constituents linalyl acetate and linalool"
The first source mentions essential oils not lavender oil and 5mL toxicity.
The second source mentions range from 5-15 mL and 2-3 mL in the context of toxic for adults and children.
The third source mentions poisoning in case of use of large amounts of lavender oil.
Therefore, combining these three sources in the article we have a violation of Wikipedia rules, i.e. classic synthesis and OR.
New information from the article "If ingested by adults in amounts as small as 5ml, lavender oil can be poisonous." is also OR and synthesis because sources are again combined to reach a personal etc conclusion. WP:SYNTH "Do not combine material from multiple sources to reach or imply a conclusion not explicitly stated by any source." Source which talk about 5mL does not mention lavender oil and mentions toxicity while source which talk abaut lavender oil talk about poison if someone uses large amounts of lavender oil. Not compatible with each other.
Cite where lavender oil is mentioned in the source or that lavender oil is in the context of the source. Expose it here or don't make baseless claims because it is violation of the OR rule.

Do you understand english? Expose source, quote, which page or context if the source talking about lavender oil. If you don't expose it on talk page, then it doesn't exist and that's OR.

My problem one, is with the phrasing of the source "Smaller Ingestions of 2-3 mL of some (note: does not say all) essential oils have been associated with toxicity in children", it says some essential oils but does not mention lavender specifically as the one being toxic at that dose. Dictionary definition of some: "being an undetermined or unspecified one".
Two, the cited guidelines also say "Toxicity depends on the dose and the essential oil ingested" so we can't generalize all essential oils to be the same.
And three, lavender is only mentioned now in two places in the guidelines as a "Common essential oil" and under "Specific oils and associated clinical manifestations".
On this basis we could, if there is a consensus to do so, include something like "Many essential oils including lavender can be poisonous if swallowed. For essential oils in general, 5ml of the undiluted oil may cause toxicity in adults, 2-3ml in children." But we should not say, or imply, that this is specific to lavender oil, because we have no source to substantiate such a comment. So, should we include something to this effect? (We don't have to.) And, how could it be better expressed?

I think your wording was also an improvement. How do you feel about the "For essential oils in general, 5ml of the undiluted oil may cause toxicity in adults, 2-3ml in children" wording suggested?

Why I think it's worth mentioning Silexan (brand name "Calm Aid")
All the RCTs I've seen on lavendar for anxiety, insommnia, and somatic symptom disorder were done with a particular lavendar oil preperation called Silexan (brand name Calm Aid), 80 mg daily. I understand the hesitancy to highlight a particular brand, but I think this is important to mention Silexan in particular, given that lavendar oil preperations vary enormously in what strains are used, distillation technique, encapsulation, dose, etc etc.
Look at this excellent blog post for more information on Silexan and a review of the studies.

I don't we think should mention the Silexan brandname. That blog post (obviously an unreliable source) is in poor English and invokes the
WP:DAILYMAIL in its argumentation. That is far from "excellent".

Source is not about environmental concerns and is not a WP:MEDRS review; case reports are primary research - discuss on talk page, if warranted
All of these are irrelevant. Of course if the environmental concerns section links a press release about a specific research paper, it ought to cite that research paper. If there are any problems with the research, then perhaps it should be removed entirely, and I encourage Zefr to improve the section if that is their concern. But removing the research paper and not the press release makes zero sense - under what circumstances would we want to link only an obsolete press release about preliminary, un-peer-reviewed, unpublished research, and forbid linking in addition the final, peer-reviewed, published, fulltext research paper...? --

Environmental factors affecting oil yield and quality would include such factors as soil and climate, and the impact of large-scale lavender farms would address effects on other crops or wildlife habitats. I did not find a suitable source for the section, so am removing it.
