Before i bought VK , everytime my son used to get cough it would take 1 week and then followed by cold for next 1 week . This time within 3 days same cough followed by cold was cured . This time i didnt have to use multiple syrups or home remedies .Though I did use one syrup . And full day i used direct request ENT serum+ACS + immune serum+perfect health serum and shield of 7 rays . And i didnt have to use any saline drops , i used VOB with ACS with intention of clear all the block and breathe easily the whole night and my son used to sleep well . I felt so happy , first time during his cold without troubling him i could heal him and give him good night sleep . Thank you so much sharat sir .
