Yes by salt i mean normal sea salt, rock salt iodine free is preferable

The process is called manske look it up, it's usually done after the acid base phases to further purify the product and eliminate unwanted compounds...

But it can be done without using any base to get a crude extract that will do the job.

Cook the seeds with some vinegar, after all the cooking is done, reduce the tea to around 200 300 ml, boil the same volume of water and saturate it with salt, mix the 2 volumes and let them cool slowly the harmalas crystals will crash out, after 8 hours filer through a coffee filer and collect the crystals.

Redissolve them in hot water then repeat the above on the new solution

When you are satisfied with the product dry the crystals and collect them

Work with whole seeds it's easier and yields purer harmalas with less effort, also you should press the liquid out of the seeds as i explained before...

It's really so easy

If you are convinced to go this way i'd be happy to write you a detailed procedure of how to do it if you want.

I'm not sure about this jello tek but it might solve the taste problem but won't help much with undesired effects.
