@Rasoul S good discussion. As much as I love simplicity, some things aren't so simple. It's difficult to say how a simple molecule or compound will effect the affect of a complex organism such as a human being. The taste of a peanut butter sandwich may trigger feelings of elation and joy in someone who recalls childhood memories of their mother making them one as they watched morning cartoons together. On the other hand, the taste of peanut in something or merely the smell of peanuts may trigger feelings of anxiety and impending doom in someone who recalls a childhood memory of the first time they experienced symptoms of anaphylactic shock from being exposed to peanuts. In these cases not only does the peanut effect their affect differently, it can effect them differently physiologically and is just one example that shows that it's not 100% correlation between a substance and how everyone will respond to it.
Other things to consider are the classification of substances, dosage and the synergistic/antagonistic nature of compounds.
Caffeine is classified as a central nervous system stimulant yet for some it can interfere with adenosine triphosphate(ATP), cyclic adenosine monophosphate(cAMP), etc. in a way that causes somnolence. Also, for some who consume high dosages of caffeine it can produce tolerance and have the opposite effect, as well as withdrawal symptoms when stopped and different effects once consumption is restarted; much like you can wear and oil today and be effected differently when you wear it next week.
With oud oils we have to consider the same things. A particular sesquiterpene MAY be classified as a stimulant but may effect each individual differently. In addition that
supposed stimulant sesquiterpene is not in isolation, it's part of the makeup of the oil along with other sesquiterpenes that may have either a synergistic or antagonistic interaction with said stimulant sesquiterpene. Also to consider would be the dosage at which said stimulant sesquiterpene becomes therapeutic and produces the desired effect. Is it one swipe, two or the entire 3gm bottle? Those are things we don't know or understand and even if science or literature tells us that a certain sesquiterpene is a stimulant it doesn't mean that it will have that effect on you; much in the same way that the literature tells us that the NSAID aspirin can reduce pain and fever in some and is thought to cause Reye's Syndrome in others.
IMO the best way forward is to, "let your conscious be your guide", experience the oil as an individual and let it tell you if it stimulates you or otherwise.
Let the oil tell the story rather than the story telling the oud, that's what we need more of in the online oud community; the story is just that and has nothing to do with the oil, it's just poetic license so don't let it be more. Some get so obsessed with the story AND the "story about the story" that they distort the oil. The "story about the story" can be seen when they make statements such as, "Until some vendors took over the scene with stories, and since one story after another it has been, to the extent that stories change the perception on products", inferring that the story is suggestive and has an effect on products at best or misrepresents the product or is a falsehood at worst. Don't they realize that the "story about the story" they tell is just as suggestive, leading and possibly misrepresents or is false about those same products? I'm quite sure they do yet will feign innocence, it's called politricks not politics and some shepherds are well versed; unfortunately most aren't fit to understand but the suggestion to the sheep is just as effective. Furthermore, the statement is problematic for two main reasons. Firstly it assumes, that unlike themselves, anyone else is focused on the story and not the oil. Secondly it assumes, that unlike themselves, anyone is incapable of making up their own mind about the oil and let what's written about the oil dictate how they experience the oil; I personally believe that most are more mentally mature, the "story about the story" seems like nothing more than agenda that does not contribute to discourse. It's disappointing that supposed esteemed, learned and mature members are still focused on telling the "story about the story".
Be an example and focus on the oils.
