This desk earns a commission on this product and spends most of this site criticising it, so it is worth setting out plainly what the case in its favour actually is.
The money is all published, and it is cheap. One bottle $89, three for $177 at $59 each, six for $294 at $49 each. Every one of those figures was in the pack supplied to this desk, which is more than most products in this category manage.
And the per-day arithmetic is the best we have printed. A bottle is 60 mL and the serving is 0.60 mL, so a bottle is a hundred days, which makes the packs $0.89, $0.59 and $0.49 a day. If what you want is a herbal morning ritual and the absence of printed amounts genuinely does not bother you, that is a coherent position and the price supports it.
The serving instruction is precise. Four pumps, 0.60 mL, once daily, morning before the first meal, shake well first — more specificity than the ingredients get.
There is somebody to call. A phone number, two email addresses, an office address and a separate returns address were all supplied, and that is how to ask the question this product cannot answer in print: what four pumps means in drops.
And the reviews are modest. Nine of the ten describe a cue rather than a result — the kettle, the first call, church coffee, the porch light — and none treats the product as a replacement for a medicine.
Against all of that: no panel, no amounts, no caution statement, no disclaimer on the face we were shown, a claim that says spray on a bottle with a dropper, and five sources of which not one supports a respiratory use. That is the trade, as fairly as we can state it.
