To get a Potion of Harming in minecraft:
Brew Awkward Potions: Use Nether Wart on Water Bottles in a Brewing Stand.
Brew Potion of Poison: Add a Spider Eye to the Awkward Potions.
Brew Potion of Harming: Add a Fermented Spider Eye to the Potions of Poison.
For an improved version, add Glowstone Dust to make Potion of Harming II or Gunpowder to make it a Splash Potion of Harming.
First off, bottle of water and some Nether Wart. That'll get you an Awkward Potion. Most versatile base potion. From there, either a Glistering Melon or a Spider eye. That'll get you a Potion of Healing or Potion of Poison, respectively. Then, add a Fermented Spider Eye. That'll turn either into a Potion of Harming. For the record, Glistering Melons are made with a Melon slice and a Gold Nugget, and Fermented Spider Eyes are made of a Spider Eye, a Mushroom, and some Sugar. Add Glowstone to a Potion of Harming to get a Potion of Harming 2. Redstone to that to change it back. And, Gunpowder to make any potion into a Splash Potion.
