Hello hopinso. I do know that black seed and its oil, lowers thee blood pressure naturally, so be careful there. If using black seed oil, you should take a teaspoon with a spoonful of RAW, UNPROCESSED, NATURAL HONEY or some natural fruit juice, in the morning before breakfast (up to an hour) and at night before bed. You can also take a tablespoon of the whole seeds and crush them and take the same way. I have also rubbed a drops of black seed oil on my hubby's achy muscles, legs, neck, back etc. so it can be used topically as well hopinso. Try taking it as advised, just two teaspoons with juice a day and see, how u feel. I pray this helps and for your recovery.
