    Honestly speaking the only research that the ’scientists’ will always do involves the increase of big pharma profits. They will never cure any disease permanently for them to make more money by keeping people reliant on drugs, and they will do everything possible to discourage others from trying other medications like herbal medicine but I thank God for my friend who directed me to Dr. Sani.I am happy to inform you all that I am finally free and completely cured of ALS (amyotrophic lateral sclerosis) after using Dr. Sani herbal mixture, the formula works like magic .Always learn to follow your heart, refuse to be discouraged because there is no problem without a solution . I am back on my feet even stronger than before thanks a lot to Dr. Sani.
    You can also contact Dr.Sani to eradicate diseases like diabetes, high blood pressure, stroke, infertility, tuberculosis, skin disease, hepatitis, fibroid etc.You can reach him through his WhatsApp number on: +2348118184266 or via Email: perfectherbalcure@gmail.com

    I want to quickly say a big thank you to DR DOHGO for what he has done for me.

I also took the same step by contacting him through his WhatsApp +2347062142293. I made an order from DR DOHGO and after taken it for 2 weeks as prescribed by him, I went for a medical test and the result was confirmed Negative. I have promised to keep telling people about the good work of this herbal doctor.

    Last month I had a hemorrhagic stroke (3.2 cm bleed) and recovered within 24 hours. By definition it is not a TIA. All that’s left is post stroke fatigue and loss of taste. Guess I am one of the lucky ones.

    My mother was able to heal her stroke problems naturally via the special guidance of an African herbal practitioner by the name Dr. Harry Obiego.
    My mom had suffered from acute bodily stroke attacks in her sixties of which had resulted from a leaking or bursting of a blood vessel (hemorrhagic stroke), and of whose condition had restricted her from partaking in certain aspects life had presented before her. Prior to the arrival of this natural remedy, my mom had experienced a great deal of difficulty in maintaining her day to day activity as it came by, this was a one condition that had resulted to the prompt loss of her job. I was really attuned to her sufferings as a daughter, as I was in every nook and cranny of the internet looking for a sustainable remedy for her condition. I had a determination to put her sorrows to an end if I could, and by Providence’s doings, I was finally able to relieve her from the humiliating sufferings she had been went through.
    It was during my ceaseless research on the internet that I had been opportune to stumble across the professional naturopathic works of an African herbal practitioner – Dr. Harry Obiego, of whom would later be my mom’s savior from her dreadful condition. There were testimonials following his gifted talent in healing paralysis naturally, and having saved quite a number in certain areas in his community. Having read all the information regarding this natural cure presented by this herbal practitioner I had been very much tempted to acquire some more information that had led me to contacting this natural healer. I was marveled at his hospitality and advice he had recommended to my mom and how his herbal supplements were able to eliminate my mom’s stroke in a short period of time after prior to the completion of the medication. It was some miraculous recovery she had experienced as she had fully became able-bodied and very active in her daily activities.
    I am so pleased at the the recovery story of my mom from this dreadful condition and would wish to use this opportunity to reach out to any facing similar ordeal to be hopeful and find a confidant like this African herbal healer in defeating their health problems. Paralysis can never be a life sentence with this natural herbal medication and would highly recommend to anyone with similar health setback.
