Note that strychnine does product noticeable visual effects. It increases all of your senses. Colors look brighter. You can see things with more detail. You can hear things better, smell more accurately. It heightens your awareness. These are all effect attributed to a low dose of LSD. But it never causes "visions", only an increase in visual acuity.

There's some ambiguity about the true species camalonga refers to. From what I've read recently, these seeds can be either seeds from the strychnos family which contains strychnine or a totally different unrelated seed (I forget the name) which contains no strychnine at all.

In some locations the shamans will substitute ingatia (Strychnos ignatii) for camalonga and consider it to have identical effects. The main active alkaloid in ingatia is well known to be strychnine.

In the past several weeks SWIM has used strychnine (extracted from Nux vomica) regularly in microgram doses (up to 500 micrograms or so), sometimes several days in a row multiple times a day.

Strychnine feels a lot like LSD.

You'll feel the following effects from microgram doses of strychnine: increased awareness, euphoria, stimulation, sense of well being, increased color perception, increased special awareness, increased sense of smell, increased sense of hearing, very pleasurable increases in sense of touch (great for sex), increased memory capacity and increases in mental concentration (it's a proven nootropic).

Strychnine is extremely dangerous and if these seeds are in fact seeds that contain strychnine, you should find out exactly how much they contain. An overdose of strychnine is extremely unpleasant and then you die. It's said to be the most unpleasant way to die. While it's safe in microgram doses, it can easily kill a person if too much is taken.

I would use extreme caution when using camalonga seeds especially since the botanical identificaion of it is unclear.

Keep in mind that other strychnine containing seeds can be used safely. Strychnos nux vomica is used in India, China, and is present in homeopathic medicines world wide. It's only safe in very small amounts. If these seeds are the ones that contain strychnine, which the shamans will substitute ingatia seeds for, then you need to be extremely careful about using them.

My advice is to stay away from these seeds unless you know exactly what you're doing.

Strychnine can be safe, but only in very small doses. The fact that the recipes I've seen that incorporate camalonga seeds seem to be highly diluted indicates they are toxic. And the fact that some shamans use ignatia as a more desired seed in place of camalonga, also indicates that at least one type of seeds called camalonga do in fact contain strychinine, otherwise shamans would not consider ignatia a direct replacement for camalonga.
