A chewing gum which contains extracts from the Pueraria mirifica (Kwao Krua) plant, makes a woman's breasts grow as well as improving their shape and tone, says B2UP, the makers of its Bust-Up gum.

The company also claims the gum fights ageing, reduces stress and helps your circulation. They say the extracts keep your muscles in good order.

Pueraria mirifica is indigenous to Thailand and Burma and has been used for hundreds of years for its medicinal purposes. The plant contains phytoestrogens, a chemical which acts in a similar way to oestrogen.

Bust-Up gum has become extremely popular in Japan.
