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The outdated perception that practitioners of traditional and alternative medicine lack formal education is now a thing of the past, and Prof.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.

Sky Train scandal: Prof Ameyaw-Akumfi fails to appear in court over medical emergency

When I was a kid I didn’t like female teachers. They would come at the beginning of the term all nice and dainty, but soon their bellies started growing for no apparent reason.
Their pretty faces will become contorted and distorted and they kept hoarding saliva in the mouth. I thought that was not very civil.
And when will the belly of Mrs stop growing out of proportion? I would wonder who was the bastard that inflicted Mrs with a balloon stomach. Yes the bastard! Who did he think he was?
Didn’t he know that Mrs couldn’t carry such a belly all by herself? And that she kept marking correct arithmetic work wrong?
I often got angry and went to my Dad to complain about the Mrs “She marked this answer wrong”.

I’d tell Papa, tearfully. “Bring it let’s see!
My Dad would look at the sum. “I think you are right,” he would say. “I wonder why she marked it wrong.”
“That woman, she is always dozing!” I’d tell my Papa. “This morning she tried to vomit, but nothing came. And half the time she is angry with everybody”.
“What might be the reason?”
“I think it is her belly. It is too large. Or is it the saliva in her mouth?”
I decided to ask Mrs why she was keeping saliva in her mouth.
The next morning I went to school and we were told that Mrs had gone on “maternity leave.” And what did that mean?
We were told that soon, she would be having a baby. Nonsense! How possibly could a baby as large as the one in Mrs stomach come out? Through which exit? They must be joking!
Sooner than expected, the class was informed that Mrs’ had delivered a bouncing baby boy. And so what? She was supposed to be in class teaching us English grammar not delivering bouncing babies.
Meanwhile, the male teacher who took over was quite different. We all noticed that contrary to expectation, his belly did not grow. At least not frontally or laterally. And he did not store saliva in his mouth. More so, he was arithmetically alert. The class was happy although he liked caning the pupils.
The man did not doze and he’d take us to PE and also teach us Christmas songs. He spoke decent English and marked the exercises on time. Then one morning he announced to us that a female trainee teacher would be coming to teach us for a while. She was from a training college. I wondered whether this one was also afflicted with a swollen belly.
PRETTY
She turned out to be a very young pretty daisy. I liked her! “My name is Miss Amoah,” she intoned. “I’ll be teaching you for the next few weeks.”
I looked at her belly. I needed to reassure myself that she was not encumbered with a ‘bouncing baby.’ My goodness! Or was it because she was Miss and not a Mrs? What was the difference anyway? “I hope you are all good boys and girls.”
“Yes Miss!” we shouted in alacrity.
“I don’t like boys who talk in class. They end up as gutter cleaners!”
We all laughed heartily and drummed on our desks. Certainly the Miss had a sense of humour in her head. How did she know that such boys ended in the gutter? And will they wear Wellington boots when doing the clean out?
“And girls who talk in class, do you know where they end up?” she asked.
“Yes!” we chorused.
“Who can tell me?”
“Farm!” one pupil said. “No!”
“In market selling tomato and garden eggs.”
“No!” said Miss Amoah.
“Hell!” (Laughter)
I raised my hand, I thought I knew this one.
“Yes you there!” Miss Amoah pointed at me.
“She’d end up with a swollen belly full of babies!”
The entire class convulsed into laughter. And it was Miss Amoah who laughed the most.
She couldn’t conjecture how I could come up with the idea of a distended belly containing babies just because a girl talked too much in class. But she realised upon a little bit of cogitation that there could be a link between talkative and babies.
DROPOUT
After all, isn’t it those who are idle talkers who aren’t serious with their academic work and end up getting pregnant and dropping out of school?
Last weekend, I watched it live on television when President Kufuor presented three cars to three lady teachers as the best teachers in Sikaman. I protested loudly. What have the male teachers been doing? Bearing babies?
My wife was overjoyed that female teachers were making a mark. But my daughter was a bit skeptical. “How were they adjudged the best?” she asked me.
“Ask your mother!”

Ethanol, the chemical compound present in most alcoholic drinks, is a neurotoxin, that is, a substance that can damage or destroy the nervous system. Someone who is drunk is, in fact, suffering from a form of poisoning.
In large quantities, ethanol causes coma and death. For instance, among students in Japan, the practice of ‘ikkinomi, or alcohol chugging, causes deaths every year.
The body is able to convert ethanol into harmless substances, but this is not accomplished immediately. If alcohol is consumed at a faster rate than the body can handle, ethanol builds up in the system and begins to interfere noticeably with brain function. In what way?
Speech, vision, coordination, thought, and behaviour are all connected with an incredibly complex series of chemical reactions in the brains neurons, or key cells. The presence of ethanol modifies those reactions, suppressing or enhancing the role of certain neutrontransmitters chemicals that relay signals from neuron to neuron.
The stream of information in the brain is thus altered, preventing the brain from functioning normally. That is why when a person drinks too much, he or she develops slurred speech, blurred vision, sluggish movement, and weakened behavioural restraints and inhibitions, all common symptoms of intoxication.
EXPOSURE
With prolonged exposure to alcohol, brain chemistry adapts to counter the poisonous effect of ethanol and to maintain normal nerve function. This leads to tolerance, whereby the same amount of alcohol has less of an effect than it would have had previously.
Dependence occurs when the brain has adapted so much to the presence of alcohol that it cannot operate properly without it. The body craves alcohol to maintain the chemical balance.
When a person is deprived of alcohol, his brain chemistry is totally destabilised and withdrawal symptoms, such as anxiety, trembling, or even seizures, set in.
Besides causing modifications of brain chemistry, alcohol abuse can lead to cell atrophy and destruction, altering the brain’s very structure. While partial recovery is possible with abstinence, some of this damage seems to be irreversible.
Neurons that die are apparently never replaced, further affecting memory and other cognitive functions.
Damage to the brain is not just the result of long term exposure to alcohol.
Research seems to indicate that even relatively short periods of alcohol abuse can be harmful.
LIVER DISEASE
AND CANCER
The liver plays a vital role in metabolising food, combating infection, regulating blood flow and removing toxic substances, including alcohol, from the body.
Prolonged exposure to alcohol damages the liver in three stages. During the first state, the breaking down of ethanol slows the digestion of fats, causing them to build up in the liver.
This is called steatohepatitis, or fatty liver. In time, chronic inflammation of the liver, or hepatitis, sets in. While alcohol can cause hepatitis directly, it also appears to lower the body’s resistance to Hepatitis B and Hepatitis C viruses.
If unchecked, inflammation causes cells to burst and die. Compounding this damage, alcohol seems to trigger the natural system of programmed cells death called apoptosis.
This final stage is cirrhosis. The vicious cycle of continuous inflammation and cell destruction causes irreversible scarring. Eventually, the liver becomes humpy, instead of remaining spongy.
Finally, scar tissue prevents blood from flowing normally, leading to liver failure and death.
Alcohol’s effect on the liver has another insidious side effect -the liver is less capable of playing its defensive role in counteracting the effect of cancer-forming agents.
In addition to favouring the development of cancer of the liver, alcohol greatly increases the risk of cancer of the mouth, the pharynx, the larynx, and the oesophagus.
What is more, alcohol makes the mucous membranes in the mouth more easily penetrated by cancerous substances in tobacco, elevating the risk for smokers.
Women who drink daily are at greater risk of breast cancer. According to one study, the risk for those who drank three or more alcoholic beverages per day was 69 per cent higher than that of nondrinkers.
POISONED BABIES
A particularly tragic outcome of alcohol abuse is its effect on the unborn. “Alcohol is far worse for the developing fetus than any other abused drug,” reported by the ‘International Herald Tribune.’
When a pregnant woman drinks, her developing chin also drinks and the toxic effect of alcohol is especial, devastating at this format stage of the fetus.
Alcohol causes irreversible damage to its central nervous system. Neurons do not form properly. Cells are killed off. Other cells end up located in the wrong place.
The result, fetal alcohol syndrome (FAS), is the foremost cause of mental retardation in newborns. Difficulties encountered by FAS children include intellectual impairment, language problems, developmental delay, behavioural dysfunction or deficit, slow growth, hyper activity, and hearing and sight disorders. Many babies are also born with characteristic facial deformities.-Credit: AWAKE

In Ghana, the Narcotics Control Commission Act, 2020 (Act 1019), prohibits the possession, use, trade, or cultivation of narcotic drugs without lawful authorisation.
The law now adopts a more public health-based model, emphasising rehabilitation and education while still maintaining punitive measures against trafficking and illegal possession.
This opens doors for religious and social actors to play key roles in prevention and healing.
How the Youth and General Society Are Typically Lured into Illicit Drugs;
One of the primary gateways to drug use is peer pressure. Many young people are introduced to drugs by friends who make substance use appear fashionable or as a coping mechanism for stress, boredom, or emotional trauma.
In urban slums and some schools, peer groups become influential in shaping behaviour, particularly when parental supervision is weak or societal structures have collapsed.
Another contributor is media influence—with movies, music, and social media sometimes glamorising substance use. Unemployment, poverty, broken homes, academic stress, and lack of religious education also contribute significantly.
Shaykh Abd al-Rahman al-Sa‘di explains that when faith weakens, individuals seek escape in destructive behaviours. Hence, strengthening iman (faith) is a critical defence against temptation.
Rescuing Victims: Rehabilitation and Social Support
Those who fall into drug addiction must not be condemned but rather supported with compassion and care. Islam emphasises mercy and hope:
“Say, O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins.” (Qur’an 39:53).
Rehabilitation centres, faith-based recovery programmes, community counselling, and mosque-based interventions are all vital tools.
Imams and scholars should be equipped with basic knowledge in addiction counselling. Collaboration with the Narcotics Control Commission and health institution can create models where religious guidance and medical treatment go hand-in-hand.
Impact of Illicit Drugs on Society
Illicit drug use damages physical health, corrupts moral values, and leads to crime and unemployment. It depletes a nation’s human capital, as youths and adults become dependent, mentally unstable, and economically unproductive. It also leads to violence, theft, and domestic abuse.
The Qur’an declares: “And do not throw yourselves into destruction with your own hands.” Qur’an 2:195)
Impact of Illicit Drugs in Schools
In Ghana, the increasing prevalence of drug abuse in schools has led to absenteeism, violent behaviour, academic failure, and mental health issues.
Some school dropouts have become part of gang culture, especially in urban areas, threatening future national development. These environments must be purified and protected with strong policy, parental involvement, and faith-based education.
UNICEF, Ghana Health Service, and Other Reports
UNICEF (2019) highlighted the correlation between substance abuse and early childhood trauma, noting that youth exposed to abuse, neglect, or poverty are more susceptible to drug use.
The Ghana Health Service’s 2022 report showed a 17 per cent rise in mental health cases linked to drug abuse, with youth between 15–35 years most affected.
Narcotics Control Commission Statistics
According to the 2022 Annual Report of the Narcotics Control Commission, over 8,000 arrests were made for drug offenses.
Cannabis remains the most abused drug, with growing concerns about synthetic drugs and pharmaceutical abuse, especially tramadol and cough syrups with codeine.
Islamic Law and Maqasid
al-Shari‘ah
The five universal objectives of Islamic law (maqasid al-shari‘ah)—preserving religion (deen), life (nafs), intellect (‘aql), lineage (nasl), and wealth (maal)—are all endangered by drug abuse.
Any initiative that protects these objectives is not just legally encouraged but religiously mandated.
Imam Al-Shatibi, in al-Muwafaqat, asserts that laws are designed not for hardship but to preserve human dignity and collective wellbeing.
Therefore, illicit drugs threaten the very fabric of what Shari’ah seeks to protect:
1. Preservation of Religion (Hifz ad-Deen) – Drug use weakens a person’s sense of religious duty. Addicts often neglect prayer, fasting, and remembrance of Allah, falling into sin and heedlessness.
2. Preservation of Life (Hifz an-Nafs) – Drugs increase the risk of premature death through overdose, suicide, or violence. Islam strictly forbids self-harm: “And do not kill yourselves.
Indeed, Allah is to you ever Merciful” (Qur’an 4:29).
3. Preservation of Intellect (Hifz al-‘A9ql) – One of the clearest reasons intoxicants are forbidden. The mind is the seat of moral judgment. Losing one’s intellect means losing the capacity for faith and responsibility.
4. Preservation of Lineage (Hifz an-Nasl) – Drug addiction often leads to moral decay, fornication, and broken families, harming future generations.
5. Preservation of Wealth (Hifz al-Maal) – Addicts squander wealth on drugs, harming families and communities. Islam commands us to be custodians of our resources.
These objectives guide the Islamic legal position that drug abuse is not just a sin, but a social threat that must be collectively confronted.
