There are two types of potions, splash potions and regular potions. Splash potions are used by right clicking, and instead of drinking the potion, you throw the potion and any affects of the potion will be transferred to any mob within the radius of the splash potion. Be warned, this includes you as well! You can make a splash potion by putting gunpowder in the brewing stand. Regular potions can be drunk, and you hold right click as you do to eat. The effects are different and are determined by what you brewed up! Some may be harmful to you (i.e. Potion of Weakness, Potion of Slowness, etc.) and some may be helpful (i.e. Potion of Strength, Potion of Swiftness, etc.)!
Redstone makes the potion last longer when you drink it.
