It is a requirement to show the names of the prescribed herbal liquids on the prescription (and on the product label) for a patient. By default, the prescription will also show the measurement of each liquid herbal on the prescription. 

In some cases, such as in clinics which have a herbal dispensary and make the liquid herbal up onsite, a clinic or practitioner may not want to disclose the amount of each herbal to the client. You can turn off the displaying of the liquid herbal measurement amounts in the Business Setup -> Prescription Settings.

Toggle the "Hide Liquid Herb Measurement on Prescription" setting to "Yes" to hide the measurement, then click on the Save button to apply the changes.
