Clear Potion (5e Equipment)
From D&D Wiki
This potion's liquid is almost clear, but close inspection reveals that there is a slight teal coloration, made temporarily more apparent by inducing movement in the liquid.
If you ingest this potion, all ongoing magical effects you have incurred from food, drink, potions, and poisons are removed. In addition, any nonmagical effects you are incurring from poisons are removed.
Effects from spells that targeted you directly instead of any of the above are not ended by this, and effects from spells that affected such food, drink, potions, or poisons that were cast above 5th level also remain.
