The four — Isaac Kornor, 55, the man; Adjoa Akobea, 46, his former wife; Joshua Kornor, 17, and Mary Yeboah, 23, their children — died in turns within four days after taking the concoction last Thursday.
The sad incident occurred at Seikwa, a village near Akyem Tafo in the East Akyem municipality in the Eastern Region.
Joshua, who was the first to drink the concoction, complained of stomach pains and died instantly, while Mary and Akobea were taken to the Tafo Government Hospital where they breathed their last on October 4.
Kornor, who was also initially sent to the same hospital, had to be transferred to the Police Hospital in Accra and was treated and discharged.
However, when he went back to Seikwa, he complained of stomach pains again and had to be conveyed to the Tafo Government Hospital on Saturday, October 5, but died the following day.
The incident has thrown the village into a state of mourning.
According to the Deputy Eastern Regional Police Commander, Assistant Commissioner of Police Mr James Abass Abaa, Isaac and Akobea, who were no longer husband and wife, were staying at Seikwa.
He said on that fateful day, Joshua, who, together with Mary, was staying with Akobea, complained of stomach pains.
He said Akobea, therefore, sent her son, accompanied by Mary, to her ex-husband to see how best they could treat the boy.
Mr Abaa stated that Kornor gave the concoction, which he claimed could cure all kinds of ailments, to Joshua to drink, after he (Kornor) had also drunk the same stuff in their presence.
Akobea and Mary, he said, also drank the concoction.
The Deputy Eastern Regional Police boss stated that within some few minutes, Joshua died, while Akobea and Mary, who had complained of severe stomach pains, were rushed to the Tafo Government Hospital, where they died the following day.
He further stated that Kornor, who later on also complained of stomach pains, was sent to the same hospital, from where he was referred to the Police Hospital where he was treated and discharged.
He said when Kornor returned home, he started complaining of stomach pains again and was rushed back to the Tafo Government Hospital where he died on Sunday.
The bodies of the four, Mr Abaa said, had been sent to the Police Hospital for autopsy, while the police were investigating to find the source of the concoction.
