Health benefits of hibiscus enormous — Prof. Raphael Nyarkotey Obu

Prof. Raphael Nyarkotey Obu is a distinguished nature path, professor of naturopathy, lawyer, legal academic, Chartered Health Economist, and Chartred Management Consultant. He is a passionate advocate for traditional and alternative medicine in Africa.
The outdated perception that practitioners of traditional and alternative medicine lack formal education is now a thing of the past, and Prof. Nyarkotey has played a crucial role in reshaping this narrative.
It is rare, if not unprecedented, for a lawyer to be at the forefront of promoting natural and herbal medicine in Ghana and Africa.
However, Prof. Nyarkotey has demonstrated beyond doubt that it is possible. His journey began as a naturopath before he pursued law in The Gambia, where he was later called to the Bar. This remarkable achievement made him the first naturopath in Africa to attain such a distinction.
Recognising his unique position, traditional healers in The Gambia urged him to use his legal expertise to advance the cause of traditional and alternative medicine, a mission he actively pursues.
As the President of Nyarkotey University College of Holistic Medicine and Technology in Ghana, Prof. Nyarkotey has been instrumental in advancing naturopathy and holistic medicine education.
He played a key role in developing Ghana’s first National Occupational Standard in Naturopathy and Holistic Medicine under the Commission for TVET (CTVET). His expertise spans naturopathic research, healthcare law and policy, law and development, theology, health economics, and the integration of traditional medicine into mainstream healthcare systems.
Globally recognised for his contributions, he has significantly influenced legal frameworks for naturopathy and alternative medicine in both Ghana and The Gambia.
In recent years, hypertension, commonly known as high blood pressure, has become a major public health concern in Ghana.
Health statistics indicate that a significant percentage of the adult population suffers from hypertension, exacerbated by poor dietary habits, stress, lack of physical activity, and genetic predisposition.
Other chronic conditions, such as diabetes and cardiovascular diseases, are also prevalent. Prof. Nyarkotey has gained widespread recognition for his pioneering promotion of hibiscus as a natural remedy for managing high blood pressure, a topic that has recently gone viral.
As a distinguished columnist for the Ghanaian Times, his insights caught the attention of The Spectator, leading to an interview to discuss the health and economic benefits of hibiscus, commonly known as sobolo.
Interviewer (The Spectator): Prof. Nyarkotey, your research and articles on the health benefits of sobolo have been trending recently. Can you shed more light on its impact on hypertension?
Prof. Nyarkotey Obu: Thank you for the opportunity. Yes, my recent studies and articles have focused on the effects of hibiscus, or sobolo, on high blood pressure. Several scientific studies, including my own research, have shown that hibiscus has antihypertensive properties.
It contains bioactive compounds such as anthocyanins and flavonoids, which help lower blood pressure by relaxing blood vessels, improving circulation, and reducing oxidative stress.
Studies indicate that hibiscus tea can be as effective as some antihypertensive medications in mild to moderate hypertension cases. However, moderation is key, especially for those already on blood pressure medications.
The Spectator: How does hibiscus work to lower high blood pressure?
Prof. Nyarkotey Obu: Hibiscus primarily acts as a natural ACE (angiotensin-converting enzyme) inhibitor, preventing blood vessel constriction, and thus lowering blood pressure.
Additionally, it has diuretic properties that help eliminate excess sodium and fluids from the body, contributing to better blood pressure regulation. Its antioxidants also combat oxidative stress, a major factor in hypertension.
The Spectator: Apart from hypertension, you also mentioned that hibiscus improves urine flow in men with prostate issues. Can you elaborate how this works?
Prof. Nyarkotey Obu: Certainly. Benign prostatic hyperplasia (BPH) is a common condition in aging men that leads to difficulty in urination due to prostate enlargement. Hibiscus has diuretic properties that increase urine production and flow, alleviating symptoms such as frequent urination and urinary retention. Additionally, its anti-inflammatory properties may help reduce prostate swelling and improve urinary health.
The Spectator: That’s interesting. What is the difference between consuming hibiscus cold versus hot?
Prof. Nyarkotey Obu: The temperature at which hibiscus is consumed affects its potency. Cold hibiscus tea retains more vitamin C and delicate antioxidants, making it ideal for boosting immunity and hydration. Hot hibiscus tea, however, releases more flavonoids and polyphenols, enhancing its cardiovascular benefits. Cold hibiscus is great for antioxidant effects, while hot hibiscus is better suited for hypertension and relaxation.
The Spectator: What about hibiscus powders, capsules, tablets, and decoctions? How do they compare in effectiveness?
Prof. Nyarkotey Obu: Hibiscus is available in various forms. Powders retain most bioactive compounds and can be added to food or drinks. Capsules and tablets offer a convenient, standardised dosage, ideal for those who prefer not to drink tea. Decoctions, where hibiscus is boiled for extended periods, may extract additional medicinal compounds. Each form has its benefits, depending on individual needs.
The Spectator: Does hibiscus help regulate blood sugar levels?
Prof. Nyarkotey Obu: Yes, hibiscus helps improve insulin sensitivity and slows carbohydrate absorption, which is beneficial for individuals with diabetes. Drinking hibiscus tea after meals can moderate blood sugar spikes and enhance glucose metabolism.
The Spectator: Can individuals with low blood pressure and low blood sugar consume hibiscus?
Prof. Nyarkotey Obu: Those with low blood pressure or low blood sugar should be cautious, as hibiscus can further lower both. It is advisable to consult a naturopathic doctor before incorporating it into their diet.
The Spectator: Can hibiscus be combined with pharmaceutical antihypertensive and diabetic medications?
Prof. Nyarkotey Obu: Hibiscus may enhance the effects of these medications, leading to excessively low blood pressure or blood sugar. Individuals on these medications should consult their doctors before combining hibiscus with their treatment regimen.
The Spectator: Is hibiscus beneficial for liver and kidney health?
Prof. Nyarkotey Obu: Yes, hibiscus has hepatoprotective properties that support liver health by reducing oxidative stress and promoting detoxification. Its diuretic effects also aid kidney health by flushing out toxins and reducing the risk of kidney stones. However, those with existing kidney conditions should seek medical advice before consuming it regularly.
The Spectator: What are your plans for the hibiscus industry?
Prof. Nyarkotey Obu: I see significant potential in the hibiscus industry and plan to promote large-scale cultivation, value addition, and further research. I aim to collaborate with stakeholders to develop hibiscus-based products and create more awareness of its health benefits. Establishing a structured hibiscus industry could provide economic opportunities for farmers, entrepreneurs, and researchers.
The Spectator: You also mentioned that sobolo could replace communion wine. Can you elaborate on this?
Prof. Nyarkotey Obu: Absolutely. I recently spoke with a pastor concerned about the rising cost of imported communion wine. Many churches struggle to afford these imports. I strongly propose Sobolo as an affordable, healthier, and locally sourced alternative.
The Spectator: How does Sobolo compare to traditional communion wine?
Prof. Nyarkotey Obu: Traditional communion wine is made from fermented grape juice and often contains alcohol. Sobolo, made from hibiscus flowers, ginger, and spices, is rich in antioxidants and alcohol-free, making it suitable for all church members, including children and abstainers.
The Spectator: Thank you, Prof. Nyarkotey, for sharing such valuable insights.
Prof. Nyarkotey Obu: Thank you as well. It’s always a pleasure to educate the public on naturopathic medicine and healthy living.

Farmers, fund and the mafia


The notion some people have about the Sikaman farmer can be amusing. It is the belief of some that immediately a struggling farmer manages to grab a loan, the first thing he does is to invite his abusua (kith and kin) home and abroad.
He organises a mini-festival using palm wine mixed with Guinness as the first course. There and then he announces that he is no longer a poor man; in effect he has ceased to be the close buddy of Mr John Poverty.
The ceremony will be consummated with singing and breakdance, a brief church service, drama and poetry recitals.
At least three bearded goats complete with moustache and four cockerels would be sacrificed in various recipes to celebrate the farmer’s broken alliance with poverty. Some would end up as fufu and light soup, grilled chicken, toasted mutton and smiling goat-head pepper soup. In short, the loan was well taken and well utilised.
The farmer’s prosperity begins right from the stomach. His idea is that if you don’t prosper in the stomach, there is no way you can prosper outside it.
Some farmer are ‘wiser’ though. When they get the loan, they promptly look for new wives. They can no longer continue enjoying one soup everyday like that. Variety is the spice of life! A new wife would bring new zest, new hope and heavenly glary into the farmer’s life. Most importantly the new wife would bring more action into his waist.
So the loan goes indirectly into promoting physical exercise for the human waist instead of the expansion of the farm, purchase of new equipment and improved seeds. Farmers of this nature are jokers, not farmers.
Is it probably because of these whimsical reasons that the banks are reluctant to grant loans to farmers? Obviously with the celebration of mini festivals and the installation of new wives, it is unlikely bank loans can ever be repaid. Of course, farmers who are more concerned about their libido can only be experts in re-scheduling loan payments and not in paying back loans.
Banks are very much concerned about getting their monies back with interest whenever they give out loans. So they demand collateral security as a requirement for the granting of loans. Some farmers actually don’t have anything they can put up as collateral except their hoes, cutlasses and wives. So they struggle through life, not going and not coming.
I do not blame the banks for not granting loans to those who cannot put up collateral. But what about those who are very serious farmers and can put up collateral. Should they also be denied?
Farming is seasonal and a farmer may need a loan only within a certain period to grow crops or breed birds. When the period elapses before the loans are granted, farmers are tempted to misapply the money because it lies idle. In fact, with idle money lying around, the farmer may be tempted to ‘purchase’ a new wife.
It goes without saying that farmers need money but for specific periods when the banks apparently do not take into consideration. Within three months in a year (main cropping season), a crop farmer must plant, nurture, harvest and sell. He applies for a loan and takes nine months or is not even granted. Meanwhile the money lies under his bed waiting to be enjoyed. Not all farmers are angels.
Now, If the government has seen and acknowledged the importance of farmers in national development and has instituted a Farmers’ Day which is a public holiday during which farmers are awarded, then government might as well also do something about funding for our serious farmers, at least the award winning ones to expand and grow since bank loans are not readily available.
Lama of Site 21, Tema, a man of great learning and of vision, has just been telling me that when a farmer gets an award, it means he knows his way about his job, is serious and diligent. According to him, most likely that such a person would also be investment-conscious and judicious in the use of his resources, and not interested in enstooling a new wife.
If government can set up a fund to assist, not with cash but by way of inputs, most of our farmers who have not had any assistance to propel themselves above sea level would be most thankful.
Interview a few award-winning farmers and they would tell you their palaver. The Overall Tema Municipal Farmer Mr Ellis Aferi and his wife Mrs Rosemary Aferi, began their Soka Farms Complex with ten fowls. The pig (a sow), was sent to a farm on a cart to be serviced and brought back breeding.
His piggery is now a real model of inspiration. “We started right from the scratch without any bank loan or financial assistance from any quarter. We placed our trust in labour, hard work and the advice of extension officers. Today we have a large piggery, poultry breeding house, mushroom and snail quarters, fishpond and beehives aside the rabbits we breed. All these without a penny from anywhere,” Mr Aferi told me just last week.
However, he bemoaned the current situation farmers are facing “We have exploited our creativity, our imagination and our muscles. There is a limit to productivity using only human labour and ingenuity. We now want to grow bigger but without funding there is little we can achieve in our bid to grow and develop.”
Mr Aferi like, his colleagues, uses about one ton of wheat bran to prepare feed for his birds, pigs, snails and fishes every week. When Food Complex was in operation, they had their wheat bran without problem. Today, there are mafia connections in the wheat bran trade.
According to all the livestock farmers I’ve spoken to, it is hard to get wheat bran from GAFCO or Irani Brothers directly. They allege that the companies prefer to sell to some wealthy women and top business-men who can buy wheat bran on conditional basis (that is together with flour and other products of the companies), than to farmers.
Then these women and businessmen through their agents resell the bran to the poor farmers at cut-throat prices. I don’t think the system is being fair to farmers. It is indeed a tragedy for the farmers who through their sweat and blood the nation is fed.
“We protest heart and soul,” one farmer yelled at me as if I was responsible for their plight. “How can I feed my birds and pigs satisfactorily if I cannot get wheat bran at the factory price? We disagree that because we are poor, things should be made difficult for us. The rich must not be allowed to exploit us like that.”
The proprietor of Soka Farms, Mr Aferi, for instance has risen from the discomfort of the dust and hardness of the earth to such an enviable height to be an award winner who now holds seminars for farmers, students and officials of organisations on his farm near the Ashiaman-Michel Camp barrier. He must be propped up, even if not with money with inputs on credit basis.
The government must think about setting up a special fund for such individual farmers to grow, while preventing them from cheats and those in the cloak of the mafia.

Mystery surrounding figure five
There seems to be something mysterious about the figure five or numbers ending in five. A few days ago I realised it was June 3, so I called my brother-in-law, to talk about his narrow escape from the disaster which occurred at circle in 2015.
It is a date that reminds the family each year of the goodness of the Lord every year since the incident. My brother-in-law had been standing and chatting with some friends at one of the shops that got burnt less than an hour before the incident happened.
Therefore for us as a family, we celebrate that day as a day of deliverance of one of us even as we sympathise with those who lost loved ones in that fire disaster. Later on after I finished talking to my brother-in-law and was reflecting on the incident and issues around it, another incident early on in that same year, came to mind.
The incident had to do with an air disaster in Europe and I began wondering if the number five in the figure 2015, had something to do with it.
Reports came through that a Lufthansa flight from Barcelona in Spain, flying to Germany, had disappeared from the radar around the Swiss Alps and that a search was being organised to try and locate it.
The result of the search established that the aircraft had crashed. What is even sad about this incident are the issues that led to its occurrence. Investigations conducted after the crash revealed that, it was deliberately caused.
It was revealed that, the pilot steeped out of the cockpit to go to the washroom. The co-pilot locked the door so no one could enter the cockpit without him opening it.
He then proceeded to set the aircraft on autopilot to crash the plane. When the Pilot realised that there was something wrong with the plane he rushed towards the cockpit, only to realise that it was locked.
He banged on the door to no avail. They tried contacting the co-pilot but he would not answer. Nothing in this world will be more painful than to see death coming and being helpless to prevent it. They could do nothing until the plane crashed.
A former girlfriend of the co-pilot revealed later to the investigators that he once told her that one day, he would do something that the world will forever remember his name. It came out later also, that he was told by his Doctor not to fly a plane again until his medical condition improves.
Apparently he had a mental problem but he kept it to himself and his employer never knew anything about his condition and he sadly killed high school students, about 60 from the same school, returning home from an educational tour in Spain.
This is one thing I have been praying against and I can imagine the grief of the parents of these students who tragically lost their lives.
In 2005, there was Hurricane Katrina which brought in its wake such a huge devastation in the United States. In that same year, an earthquake occurred in Kashmir resulting in over 86,000 people losing their lives, again note the last digit of the figure 2005.
I am therefore inclined to believe that we need to intensify prayer this year, 2025 to avert disaster. History has a way of repeating itself. Until I grew up, especially at the secondary school level, I wondered why we should study history and that apart from it being a reminder of dates on which certain events occurred, there was really no use for it.
I now know better that it is the basis for forecasting future events. Our teachers did not help us by not telling us the importance of history, maybe I would have become the National
