You can buy the blueprint for the White Seagull material in "The Witcher 3" from the female herbalist in Baiguoyuan. On the southeastern island of the archipelago, Halviken, the tavern owners have many and cheap materials. Then, in the hotel in Keldro Port in the Archipelago, the alchemist merchant in Beauclair City in the Blood and Wine DLC has a full set of alchemy materials, such as decomposer, binding agent, ether, mercury, etc.

The materials required by the White Seagull in "The Witcher 3" are Mandala wine, cherry wine, and alchemy blueprints. Mandala wine and cherry wine are rarely found. Most of them need to spend crowns in the tavern. Go buy it, this is where you spend the most money in the middle and early stages.

The female herbalist in Baiguoyuan sells blueprints. You can buy wine in various pubs. It is recommended to use them before they are used, because the materials consumed by meditation are consumed in order from high to low, and White Seagull will be used first.
