Naturally occuring drugs.

dophamine... occurs naturally in basal ganglia (regulation of movement) and andrenal medulla...metabolic precursor of norepihephrine and epinephrine
yohimbine...from Pausinystalia yohimbe. An alkaloid with stimulant. An alpha-2 antagonist. Can be used to treat erectile dysfunction.

cocaine...from the leaves of coca plant. Also from alkaloid group.
strychnine...from the seed of strychnine tree.

Many drug that occurs naturally can be found from alkaloid group... Thus, a new question arise :
"Ilmu ni, biar ingat sampai mati. Jadikan 'Gagal jawab dalam kuiz tempohari' satu lonjakan sumber tarbiyah bahawa ilmu bukan semata-mata untuk kuiz. Jadi, jika suatu hari nanti,si cucu akan bertanya...
"Ape contoh naturally occuring drug..?"
Dan kau boleh jawab sambil tersengih sambil menampakkan gigi palsu....
"atropine, yohimbine, cocaine, epihephrine, dopamine, norepinephrine!"
"Wow... nenekku.." balas si cucu dengan bersinar matanya.. tanda gembira =D "...
Wallahu'alam.
