This syrup has a deep blue colour, and a very agreeable flavour. The colour, however, which constitutes its chief value, is apt to suffer by keeping; and thence the syrup is often counterfeited with materials, the colour of which is more permanent, and which are more easily obtained. This fraud is easily detected by adding a little acid or alkali to a portion of the suspected syrup: if it be genuine the acid will change the blue colour to red, and the alkali to green; but if it be counterfeit these changes will not take place, except in the case of the juice of red cabbage being substituted for violets: but in this case the fraud is a very innocent one.

Medical properties and uses. - This syrup acts as a gentle laxative when given to infants; but it is chiefly used as a test of the presence of acids and alkalies.
