Love

Love is a custom brew effect added by the Witchery mod. When a passive mob (excluding NPCs such as villagers and including wolves) is under the effect it will attempt to reproduce with any nearby mobs of the same type, in the same way as when it is given its respective food item. The Love effect does not affect the world in any known way. It can be added to a custom brew in a Witch's Cauldron with a Poppy. Lengthening the duration of the effect (with Redstone, Obsidian, and a Minedrake Bulb) will increase the amount of time the affected mob is in love mode while increasing its power level (with Glowstone Dust, Blaze Rods, and Charged Attuned Stones) won't change anything.
