Standardized herbal extracts allow manufacturers to produce herbal formulas consistently from batch to batch. They also can be used to formulate liquid concentrates, capsules and tablets, among which liquid concentrates are still most effective. Unlike tablets and capsules, liquid eliminates the fillers, which can be harmful to the body over time. Capsules and tablets can be considered for healing ailments when those herbs are not soluble or hard to formulate into good tasting combinations. Still modern laboratory technology thus far cannot identify all of the properties in all herbs.
Many active ingredients remain to be standardized.
However, these unknown ingredients are still playing integral roles in maintaining proper health. References available from publisher.
