Does slim green tea with ginseng really work? what are some side effects?

i was shopping and saw a box of slim green tea. it doesn't have any information on the box just what it does and doesn't contain such as no sugar,artfical colors,flavors and no preservatives. The key ingred. are ginseng root, crataegi fructus, ailsmatis Rz, sennae folium many more and green tea as well. it is also 100% natural.|||ginseng as u kno is very healthy and it actually makes ur high blood pressure come down to regular pressure.
