I'm curious what you mean by "commitment" to rue?
I read a few reports a couple years back that rue works best when taken consistently over many days. Is that what you mean by it?
also, what's your preferred protocol for rue/harmalas?
By that, I meant showing a clear interest in the plant - its history, its phytochemistry, its pharmacology - engaging with it, and, in a sense, taking the time to get to know it. It's not something one should rush into, it takes time for harmal to reveal its potential and potency. Regular practice with it is part of the commitment, it allows one to feel more confident with it, to experience fewer adverse effects over time, and to know the appropriate doses for a given purpose.
Part of commitment is also trying all approaches to chose appropriately the most suitable for a given need at a given moment, weighing the pros and cons. There are several approaches and ROAs, involving different levels of commitment, range of (adverse) effects, duration and so on.
Currently I mostly use home made extracts because of convenience, dosage accuracy and ROA versatility as it can be taken orally, sublingually and smoked/vaporized (by making infused herbs). It's also my preferred approach in a (near) daily basis as you extract once and you're good for weeks, with the option to adjust the dose day by day according to your daily needs.
I love tea too but it only can be taken orally and introduces more dosage randomness (method of preparation, seeds potency variability). It can also be more nauseating. I took rue as tea for years - about once or twice a week on average - but once my frequency of consumption began to increase and also when I began sharing it more and more to introduce people to DMT, I found extracts to be more convenient and more suitable.
Chewing then swallowing seeds is another approach, the most straightforward in terms of administration. It is considered as the most "full" approach in terms of effects but it can be more upsetting on the stomach, still less accurate dosage wise than extracts, and it's more difficult to share with newcomers as not everyone is necessarily comfortable with the idea of chewing on a certain amount of seeds for a while before swallowing them.
Seeds can also be powdered and taken in capsules but the use of capsules adds another variable, results can be less homogeneous, less consistent. It provides a more bearable way to consume them though.
I clarify all this because, from my perspective, there is no single "best" approach; rather, there is the approach that for one is most suitable at a given moment, within a specific context, and for a particular purpose. This is why it is necessary to practice them all - to develop the broadest possible toolkit and be able to choose the one that best fits each situation, whether it's for medicinal use, entheogenic use or both.
