Is drinking Schweppes Gold halal or haram due to the presence of Centella asiatica in it?

The dinar herb (hops) is a plant used in beer making and may be eaten boiled. The ruling on its prohibition depends on whether it is an intoxicant or a narcotic. If it enters into medicine or food in a small, consumed proportion, or transforms into a non-intoxicating substance, then there is no harm in consuming it.
