Bladderwrack refers to brown algae that are found on the northern Atlantic and the pacific coasts of United States. The bladderwrack stem is known as thallus and can be employed medicinally. The bladders are air filled pods and hence this algae floats. The bladderwrack is also called kelp. Bladderwrack thallus is useful in soothing inflamed and irritated tissues. This is also used historically as a laxative. It is also observed that people residing adjacent to seas or oceans have low rate of hypothyroidism owing to iodine rich food and seaweeds such as bladderwrack.

As bladderwrack is another type of seaweed it has excessive iodine and consuming excessive iodine results in health problems.

Garcinia Cambogia is a small fruit that looks just like a small size pumpkin. An extract from its fruit and rind has been used to prepare various products mainly for weight loss. This herb, which is mainly found in India and some parts of Asia, is believed to suppress appetite and enhance fat-burning due to the presence of hydroxycitric acid (HCA) in the extract. This is how it works - HCA inhibits an enzyme called citrate lyase that plays an important part in converting excess carbohydrates into fat, but when it is inhibited, the body burns the extra carbs. While animal studies have suggested reduced food intake and decrease in body fat, human trials have not been so conclusive.
