Yohimbe.

If people wanted to obtain a legal hyperalert sexually aroused state, they might find some yohimbe and brew it up by simmering a quart of water with 1gm of ascorbic acid to 5 gm yohimbe until there's only 50% of the original water volume left. Add a lot of sugar afterward. Mixes synergistically with sassafras and pau-d'arco if you're adventurous and would like to cure your ills and get a hard-on at the same time. However, most people who have tried yohimbe have been disappointed. They didn't know know you need to brew it 20 to 30 minutes at approx 200x with an organic acid to release the alkaloid components.

The active alkaloid, yohimbine bitartrate, is the component of the only allopathic medicines known to cause erection in impotent males and approaches the concept of an aphrodisiac. Yohimbine bitartrate particularly affects nerves and changes blood flow regulators in the genital area. The medical texts never mention that it does the same thing to women, showing a typical disregard for female erection.

In the best case scenario this decoction will cause many users get a melting spinal sensation and extreme epidermal sensitivity with high interpersonal perception and melding. It can be extremely sexually arousing...or at least all the signs and signals are there...

And the worst case scenario for yohimbe? - well, you have to remember ethnographic reports documenting cases of some African tribes drinking it in copious quantities in pre-raid rituals to suppress fear and jack up physical aggressiveness. After getting to the point where they were bouncing up and down so much they looked like a mosh pit full of spears, they'd run 10 miles over to the next village and kill off most of the neighboring tribe, stopping only to rape the dogs, cattle, women, children, surviving males, dead bodies, water jugs and tree boles before running back home. I'm not sure this is something we need downtown on Friday night.

Yohimbe Caution: it will keep both partners up all night. In the male of the species this becomes really inconvenient and irritating as after a few hours an erection becomes more of a liability than an asset - especially as this aspect continues long past the point - as long as 8 hours - where you'd like to go to sleep and there's this turgid log attached to you that won't go away and is just beginning to ache.

Note on the Caution: A warm bath can help with the log-on problem, as can gentle massage. However this should be avoided for at least four hours after ingestion because of the effect of raised body temperature on metabolism of the alkaloid - ie, heat could intensify the stimulant effects.

Females are not exempt from this - it has the same effect on them, although it is easier to sleep on.

A possible downside of this erectile effect in high doses is the danger of blood vessel damage and gangrene in the penis resulting from the localized poor circulation condition known as penile erection.
