Regulatory evidence by market

No rule for this ingredient has been imported for any of the 13 markets tracked here.

That describes this inventory, not the law. No imported rule is not evidence that an ingredient is permitted: a rule may exist under another name or identifier, or in a dataset not yet imported here.

Arecoline Hydrobromide

Arecoline is found in nuts. Arecoline is isolated from betel nuts Arecoline is an alkaloid natural product found in the areca nut, the fruit of the areca palm (Areca catechu). It is an oily liquid that is soluble in water, alcohols, and ether. Owing to its muscarinic and nicotinic agonist properties, arecoline has shown improvement in the learning ability of healthy volunteers. Since one of the hallmarks of Alzheimer's disease is a cognitive decline, arecoline was suggested as a treatment to slow down this process and arecoline administered via i.v. route did indeed show modest verbal and spatial memory improvement in Alzheimer's patients, though due to arecoline's possible carcinogenic properties, it is not the first drug of choice for this degenerative disease. Arecoline has been shown to exhibit apoptotic, excitant and steroidogenic functions (A7876, A7878, A7879). Arecoline belongs to the family of Alkaloids and Derivatives. These are naturally occurring chemical compounds that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Also some synthetic compounds of similar structure are attributed to alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and more rarely other elements such as chlorine, bromine, and phosphorus.
