Standardized herbal extracts or phytochemicals are the concentrated dried residues of a fluid extract prepared from herbage. Normally the fluid (solvent) used for extraction is critical since it must "extract" (or bring out of the herb material into it) all of the important medicinal ingredients within the herbage. The solvent varies as per constitution of herb and ranges from water to alcohol to even liquid carbon dioxide coupled with criticality of extraction temperature and length of time. This dried residue is shifted to vacuum drying (freeze-drying, or lyophilization) for final phytochemical product.
There is ongoing debate between standardized herbal extract and whole herb to be

Essential oils are volatile and liquid aroma compounds from natural sources, usually plants. They are not oils in a strict sense, but often share with oils a poor solubility in water. Essential oils are produced in various internal and external glands of certain flowers, leaves, barks, wood and roots. Chemically these oils are mixtures, usually very complex, of terpenes, sesquiterpenes, their oxygenated derivatives, and other aromatic compounds. Many contain 20 to 30 constituents covering the entire range of organic materials.

“Aromatic” does not have the usual chemical meaning in the essential oil business. An aromatic chemical in this case, is any compound that has specific, useful odour. But, it’s a lingering mystery whether the plant gets any specific benefit from its essential oils.

Phytochemicals are non-nutritive plant chemicals that have protective or disease preventive properties. There are more than thousand known phytochemicals. It is well-known that plants produce these chemicals to protect themselves but recent research demonstrates that they can protect humans against diseases. Some of the well-known phytochemicals are lycopene in tomatoes, isoflavones in soy and flavanoids in fruits. They are not essential nutrients and are not required by the human body for sustaining life.

There are many phytochemicals and each works differently. These are some possible actions:
