My mother-in-law is a nurse and told me I shouldnt gargle with salt water for my sore throat/tonsillitis because I have hypertension and it will cause my blood pressure to go up.  I dont plan on drinking it, simply gargling and spitting back out.  Can it raise my blood pressure?
Hi, dairy have gone through your question. I can understand your concern.  You have sore throat.  You should go for warm saline water gargling.  There is no harm in that. It is very helpful.  It will not increase your blood pressure.  Don't worry about blood pressure.  Just be relaxed. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
