The best plant based one (Opium) is likely to get you arrested as would Cannabis (proven to help treat a wide range of heath problems).
All anesthetics are basically poisons
Willow bark and cloves are mild painkillers and not really up to what you're asking about (that said, if you're going to reduce my fracture I'd rather have willow bark then nothing)
Frankly apart from nitrous oxide* almost anything that will work well is illegal to have....Mostly due to abuse.

Just a passing thought, as I'll be covering the use of both willow bark AND clove oil next year. There's a difference between a local anaesthetic and a painkiller. Willow bark contains the active ingredient salicylic acid, the active ingredient in aspirin. It's something you'd take to dull a current pain, just like aspirin, rather than a local anaesthetic, which is how clove oil works. Salicylic acid is, oddly enough, also used in facial scrubs as it's a natural exfoliant. It has a number of interesting and useful properties - http://www.chemicalland21.com/specialty ... 20ACID.htm
But you wouldn't use it before an op, because analgesic isn't the same as anaesthetic!
