Vanilla Minecraft has some unused effects hidden in the code. This mod makes potions with these effects brewable in survival. Additionally, there are some new trade-off potion effects adding stronger effects combined with some bad effects (inspired by the Potion of the Turtle Master).
Potions can be turned into Splash Potions, Lingering Potions or Tipped Arrows the common way (Gunpowder, Dragon Breath, Arrows). Most Potions can also be increased in length and/or strength (Redstone and Glowstone Dust).
Keep in mind that, yes, not all potions are useful for drinking, but that is why you can either throw them or put them on to arrow tips.
Potion recipes should now also show up in JEI!
Potions List
Potion Name followed by the recipe and maybe followed by a description if not obvious. [R] means you can combine it with Redstone to increase potion duration, [G] means you can use Glowstone Dust to improve strength, [G/R] means you can do both (either or).
Milk Bottle
Actually not a Potion, but I mention this here to make sure people see this. Basically, Milk Buckets are not stackable, so I added Milk Bottles instead. These are stackable and can be obtained by just right-clicking on a Cow while holding an empty Glas Bottle. Drinking these remove all effects that are curable by Milk Buckets.
Potion of Blindness [R]
Potion of Invisibility + Spider Eye
Potion of Nausea [R]
Awkward Potion + Slime Ball
Potion of Health Boost [R/G]
Potion of Regeneration + Honey Bottle
Adds more red hearts temporarily. These can be regenerated (if lost) for the duration of the potion.
Potion of Absorption [R/G]
Potion of Healing + Honey Bottle
Gives you yellow hearts temporarily. These can not be regenerated if lost.
Potion of Glowing [R]
Thick Potion + Prismarine Crystals
Makes you glow like when hit by a Spectral Arrow.
Potion of the Underground Explorer [R/G]
Awkward Potion + Poisonous Potato
Ideal for safe mining journeys: You mine faster and you are saturated for the duration, but you become more vulnerable (you have less maximum health).

Awkward Potion + Chain
Gives you actual armor properties. Stacks with already worn armor.

Highly situational: Your max health (red hearts) gets reduced, but you gain a lot more absorption (yellow hearts), increasing your hp by a lot initially!

Yes, 2 different recipes for this one. Combines the Potion of Leaping and Potion of Swiftness into one.
