I figure it can't hurt, right?
Here are some of the best I've read up on:


Garcinia cambogia. This herb is rich in a substance called hydroxycitric acid, or HCA, which is believed to promote weight loss by blocking the conversion of sugars and starches into fats. In addition to inhibiting fat production, it is also thought to aid in suppressing appetite by raising certain brain chemicals, such as serotonin.

Banaba leaf. A medical plant used in Southeast Asia, this herb claims to lower blood sugar and promote healthy insulin levels that are related to appetite. Keeping these areas regulated may moderate a person's cravings and caloric consumption.

Psyllium. This is a natural form of fiber. It has been known to aid in weight loss by creating a sense of fullness, especially when taken before a meal or with a large glass of water, to help with absorption.

Guarana. Produced mainly in Brazil, one of this herb's main ingredients is caffeine. Combined with other compound, namely theobromine and theophylline, guarana is a nervous system stimulant that may suppress appetite and promote weight loss. Five hundred to a thousand milligrams yields approximately the same caffeine levels as 2 cups of coffee per day. Ingesting more can cause nervousness and irritability.

White willow bark. This herb carries anti-inflammatory properties and increases norepinephrine levels, which may stimulate fat metabolism, and lead to weight loss.
