Power Herbs can only be purchased from the item seller at the southwestern Exchange Service Corner kiosk in the Battle Frontier. Each Power Herb will cost 32 BP.
The Power Herb is a Held Item that allows “charged” moves with two parts (like Solar Beam or Skull Bash) to be used in just one turn. The item is consumed after one use.
Getting Power Herbs
Power Herbs can only be found in the Battle Frontier, which is the huge building to the northeast of the Pokémon Center in the Battle Zone’s Fight Area.
You’ll only be able to access this area after you’ve defeated the Elite Four and Champion at least once.
After entering the building directly next to the Pokecenter, continue through the Entrance Hall and head through the door on the northern wall.
In the middle of the Main Hall will be several kiosks making up a central marketplace. This is the Exchange Service Corner.
Speak to the clerk at the southwestern kiosk (the one with the blue and white striped canopy).
Scroll through her inventory until you find the Power Herb listing.
Each Power Herb costs 32 Battle Points (BP). And you can only win BP by fighting in the Battle Frontier’s various facilities.
What Do Power Herbs Do?
Power Herbs are Held Items that shorten two-part “charge” moves into single-turn attacks. This means some of the strongest attacks in the game can be used without the drawback of leaving your Pokémon defenseless for an entire turn.
This item works on the following moves:
- Razor Wind
- Shadow Force
- Skull Bash
- Sky Attack
This sounds like a better item than it is, if you overlook the “single-use” part of the description.
Are Power Herbs Worth Using?
In a typical single-player playthrough of Platinum it’s hard to justify using Power Herbs.
Not only is the item only usable once per battle, but in a single-player game the item is consumed permanently after one use.
32 BP is far too steep a price to pay for an item that is destroyed after its first use.
Power Herbs are much handier in competitive play, since they don’t disappear. But they can still only be used once per battle.
There are much more useful strategies in Platinum you to replace a Power Herb with; for instance, if a Pokémon with the moves SolarBeam and Sunny Day is also holding a Heat Rock, Sunny Day will last for eight turns instead of five.
In that scenario, the Heat Rock essentially grants the effects of several Power Herbs in one item.
The greatest use for Power Herbs is within the facilities of the Battle Frontier, many of which involve fighting several quick battles in rapid succession. Because Held Items don’t disappear in the Battle Frontier facilities.
So with a Power Herb you can enter every battle with an overpowered move ready to go with no drawbacks to speak of.
