Instead of dragoon Blood may be used Iodine Solution 5 %.
in the matter of fact- iodine docent disturb your inner energy flow, however when I got dragoon blood and apply it- it was same as something rip out big hole out of mine chest, if you sensitive to herbs spirits- you may be careful apply dragoons blood to your scars.
The spirit of Sapo made his work, and after mine experience I can recommend Iodine solution 5% to anyone who is sensitive to any external energies.
peace
