A balm that when you rub it into your sore muscles it heats up and soothes them. It is one of the world's very effective quality products. The thanks for this wonderfull rubbable balm goes to Aw Chu Kin. A lover of all, he studied endlessly, trying to releive the suffering of the workers in rice fields and discovered certain herbs - such as camphor, clove and menthol - really brought relief as mild analgesics, for countering irritation, and promoting blood flow. The entrepreneurial side fell to his two sons Aw Boon Par and Aw Boon Haw who brought the product to market intially in Singapore and then to the world. It was Aw Boon Haw who lent his name, meaning Tiger, to the remedy. For some reasons this is not an over the counter remedy in some places.
