Gambian President Yahya Jammeh said that dozens of HIV/AIDS patients in the tiny West African state have been cured with his secret concoction of boiled herbs.

Jammeh first announced he had found a natural remedy to cure AIDS in 2007, stirring anger among Western medical experts who claimed he was giving false hope to the sick.

"Who am I to expect that everybody would praise me," Jammeh said in a state television broadcast on Sunday evening, announcing that 68 patients had been cured and discharged from a treatment center.

"Just as the Prophet Mohammed prevailed and established Islam ... I also prevailed to cure HIV/AIDS to the point that 68 are being discharged today," he said.

The World Health Organization and the United Nations have said Jammeh's HIV/AIDS treatment is alarming mainly because patients are required to cease their anti-retroviral drugs, making them more prone to infection.

The president said the cured group was the seventh batch of HIV/AIDS patients undergoing his herbal remedy to have been discharged since the treatments began five years ago.

Jammeh came to power in Gambia, a sliver of land on Africa's west coast that is popular with sun-seeking European tourists, in a bloodless military coup in 1994.

He is accused by activists of human rights abuses during his rule, and most recently drew international criticism for executing nine death row inmates by firing squad.

Jammeh said on Sunday that his government would fully integrate "natural medicine" to all the country's hospitals, to complement Western medical techniques.

Other African leaders have drawn criticism for extolling the power of natural remedies to combat AIDS.

The administration of former South African President Thabo Mbeki was ridiculed for denying there was a link between HIV and AIDS while prescribing  treatments such as beet root instead of internationally proven medicines.

The HIV rate in Gambia is relatively low compared to other African states, with 2 percent of the country's roughly 1.8 million people infected, according to the United Nations.
