Well @Ślepy Fotografer can perhaps try developing film in his recipe without Ascorbic acid and tell us what he gets.
It shouldn't be impossible to obtain a small quantity of pure thymol, mix it up with some sodium carbonate, and see (first) if it will blacken a piece of leader in the light.
Exactly my words when a neighbor handed me a Christmas present. She said it was neither, so it's still sitting unopened.If I can smoke it or eat it and get high, I am all in.
Ever thought how thyme was used? This should give you the answer.No idea, I thought Thymol was used mostly as a disinfectant. Do you have any reference that you can share?

Well, I couldn't find any thyme, so someone else needs to check that. But a handful of mint from outside, steeped in 300ml of boiling water with a tablespoon of oregano and a tablespoon of rosemary, strained, then half was mixed heartily with a heaping spoonful of borax developed, in 8 minutes, totally blank film. The other half was mixed with a spoonful of sodium carbonate and is doing a good job of washing the film leader that's been soaking in it for 15 minutes - but it's not turning black.
Any idea what kind of mint?
Dancing dogs! Sign me up.Apples and bannanas contain catechol - it's the catechol oxidizing that turns the fruit brown when it is exposed to air.
Fresh apple juice (straight from the fruit and not yet turning brown) and s. carbonate might make a developer. Or might not...
I think vegetable developers are in the same class as dancing dogs - it's not a matter of how well the dog dances but that it dances at all.
My experiment was very limited (a few frames at the end of the roll, bad light) but it works,

Take Thyme out of your formula and it will still work.
From what I read at the time, I doubt it.
No problem. There are many claims being made about herbal and edible developers without proper testing. It doesn't take much effort to do a test where you develop two strips of exposed film, one using your favourite herbal developer and other with the same developer without the herb (adjust pH to be the same as the other) and convince yourself and the world that herbs did something that Ascorbic acid couldn't.
Sure, but it works both way, why don't you test your theory that the biggest part of the caffenol recipe is bogus and the litterature about the role of phenols is wrong ? .
No problem in believing you, but I definitely don't understand something here, might be me.. . you say that you used polyphenol rich herbs and had similar results, meaning no developement or working development ? did you used ascorbic acid and washing soda with your herbs ? what did it prove in the end ? you implied in your first reply that vitamin C alone with something to get the PH right would work so i'm confused.. what exactly should one test ? ThanksI didn't say Caffenol is bogus, so please don't misquote me. I have experimented with herbal developers and like @Don Heisz I too found that they don't work as claimed. As far as Daniel Keating is concerned, Jay DeFehr and I tried to replicate his work independently after he posted his results in a Facebook group - Jay with exactly same herb Daniel used and I with poly-phenol rich Indian herbs. Our results were similar - no evidence that the herbs did any development except possibly alter pH of the developer. You don't have to believe Daniel or me or anyone- you can do a simple test and find out yourself.
They didn't add instant coffee for it's pleasant smell when they designed caffenol in the 90's
