Valerian iyo hurdadu waxay si dhow ula xiriirinayeen kun sano. Horeba Giriigii hore, dhakhaatiirta Hippocrates iyo Galen waxay ku taliyeen isticmaalka ka hortagga hurdo la'aanta. Qarniyadii dhexe, dhakhaatiirta dhirta waxay u arkeen inay tahay dejiye qumman. Intii lagu guda jiray dagaalkii koowaad ee aduunka, xataa waxa ay ahayd wax caadi ah in laga helo jeebabka askartii u adeegsan jirtay in ay dejiso dareen-celinta ka dhalatay duqaymaha. Inkasta oo wax walba, iyo la yaab leh sida ay u muuqato, cilmi-baarista kiliinikada ayaa wali ku guuldareysatay inay muujiso waxtarkeeda ka soo horjeeda hurdo la'aanta. Daraasadaha qaarkood waxay muujinayaan dareenka hurdo roonaanta^1,2 iyo sidoo kale hoos u dhaca daalka³, laakiin fikradahaas laguma ansixiyo shuruud kasta oo ujeedo ah (waqtiga la seexdo, muddada hurdada, tirada soo kicinta habeenkii, iwm.).

Komishanka E, ESCOP iyo WHO si kastaba ha ahaatee waxay aqoonsan yihiin isticmaalkeeda lagu daweeyo cilladaha hurdada iyo, sidaas awgeed, daalka ka dhasha. Valerian waxaa lagu qaadan karaa gudaha 30 daqiiqo ka hor wakhtiga jiifka: ku shub 2 ilaa 3 g oo xidid qallalan 5 ilaa 10 daqiiqo 15 cl oo biyo ah karkaraya.
