Hi and thank you so much for this query. I am so sorry to hear about this kerosene that your friend consumed unknowingly. It is already in her system and there is nothing much that can be done at this time. however, the good news is that her doctors should monitor her closely and treat for any abnormal symptoms that develop. For example, if the blood pressure is dropping and she is having symptoms of dizziness, headache, disorientation etc, her doctors would administer fluids to her. Please, encourage her to be double conscious when she next consumes from containers she is not used to to avoid future more dangerous and even potentially fatal accidents. II hope you find the above information helpful.Thank you so much for using our services and please feel free to request for clarifications or ask for more information if need be. I wish you the best of health. Dr. Ditah, MD.
