In FFXIV, Watered Cordial is an item commonly used during Mining, Botany, and Fishing to rapidly restore GP. This allows you to more quickly use skills when harvesting from the next node. With a recast time of two minutes and 20 seconds, or two minutes and six seconds for HQ Water Cordials, you will need to wait some time between uses.
As they only restore 150-200 GP depending on the quality, Hi-Cordial is now considered to be the default option for most players. Those cannot be crafted, however. If you’re looking for an easily craftable and better alternative, try out regular Cordial, which restores more GP.
One other, minor advantage to Watered Cordial versus Cordial and Hi-Cordial is its short recast time. It can be used more frequently than any other similar item currently in FFXIV.
