The Chief Medical Director, Lagos University Teaching Hospital (LUTH), Idi-Araba, Professor Akin Osibogun, on Sunday, advised Nigerians against indiscriminate use of herbal mixtures.
Osibogun told the News Agency of Nigeria (NAN) in Lagos that many herbal mixtures were taken raw and could destroy vital organs in the body.
According to him, these raw mixtures contained chemicals that had also not been analysed scientifically to determine their dosages
“For instance, a very potent medicine that is used for heart conditions, ‘Digoxine‘, is obtained from Lanatal leaves, so it’s obtained from herbs.
“But, we need to do more research to get the acute ingredients from the herbs and separate them from harmful products that are also in those herbs.
“And then, we must also determine the exact dosage that is required to help a patient.
“So, until we have done that research, it is not good to just ask people to be drinking something without dose, without measurement and without quantification,” he said.
Osibogun said some unanalysed herbs could damage the liver and kidney, because the organs worked all the time to eradicate the harmful ingredients in the body.
He said it was important to talk with a doctor before using herbal supplements.
He also urged the public to investigate the potential benefits and side effects of herbal supplements before use.
“Herbal medicine is popular among Nigerians, but they appear to be ignorant of its potential toxicity.
