Abstract

L'invention concerne un liquide pour cigarette électronique, comprenant du salidroside, la teneur en salidroside du liquide pour cigarette électronique représentant de 0,09 % à 10 % par rapport au poids total du liquide pour cigarette électronique. Après atomisation du liquide pour cigarette électronique, le salidroside contenu en son sein peut être atomisé conjointement avec le liquide pour cigarette électronique et finalement absorbé par le corps humain. Le salidroside présente des fonctions anti-fatigue, anti-vieillissement, de régulation immunitaire, d'amélioration de la tolérance à l'oxygène hypoxique et de protection cardiovasculaire sur le corps humain, et peut rendre la sensation en bouche du liquide pour cigarette électronique après atomisation plus riche et plus délicate et peut enrichir l'arôme de l'aérosol, ce qui permet d'améliorer l'expérience de l'utilisateur.
