Can drinking a slimming tea and taking a prune extract supplement at the same time kill you?

[Stacey W]

I took five of these all natural herbal pill which contain prune extract, aloe vera, and psyllium -- it's safe to take five a day -- and I almost immediately afterward drank this super slimming herbal tea which contains senna leaf, whorled mallow leaf, persimmon leaf, papaya leaf, and licorice root. Both are supposed to be all natural herbal laxatives, however now I am paranoid that I have taken some lethal combination of herbs; does anyone know any information on mixing these herbs together?/
