Sangre de Drago or Dragon's Blood has been used by indigenous tribes of South America 
for millennia. The first written data about it's usage and property as wounds healing remedy was recorded by Spanish explorer and "student of nature" Bernabe Cole (Born in  Spain, 1582; died in Peru, 1657). 
In 1991 to 1995 during epidemic of cholera in South America, some ethno-botanical/ ethno-medicinal researchers from Shaman Pharmaceutical Inc.- (San Francisco based pharmaceutical company, specializing in research of tropical plants for medicinal purposes), have noticed how shamans were using Sangre de Drago sap for diarrhea, and that lead to extensive study in the areas of the plant's chemistry, that resulted in three products: Provir^TM - an oral product for the treatment of diarrhea, Virend^® - a topical antiviral for the treatment of herpes, and Nikkomycin Z - an oral anti-fungal product.

There are over one hundred products, made by pharmaceutical companies and sold in the drug stores around the world, with primary components plant derived.
 
South Americans use the sap on wounds to stop bleeding, on burned skin to create kind of "skin layer" to stop infection and pain, and to speed up healing process. Sangre de Drado accelerates healing and is used for generations to seal and protect external and internal injury from infection. It is also very powerful remedy to treat skin touched by poison ivy (our own experience).
Latex/Sap of Dragon's Blood has been used in oncological therapy, it has been used to heal ulcers (throat, gastric, duodenal, etc), tumors, etc.

Taspine is the alkaloid compound present in Sangre de Drago.
The Dragon's Blood we offer is the top quality:
Latex/Sap liquid     taspine 2,5 - 4%
Latex/Sap dried powder  taspine 20%
Bark powder          taspine 0.28%

Usage:
External: Few drops of pure sap apply onto affected skin area, and let it dry (carefully, it leaves a stain on a cloth).
Few drops of Sangre De Drago mixed with Cat's Claw tea makes very powerful antiseptically - vaginal bath (yeast infection, fungus, etc). 
 
Internal: 10 to 15 drops of Sangre de Grado with a small amount (1-2 tablespoons) of water or juice (cranberry or grape) three times a day between meal (1 hour before or after).

One of our Client from California gave us the following tips (Many thanks to Roberto): 
1) Hypertension:
   Prepare the Cat's Claw/Una de Gato tea as suggested (see Herbs from Peru on tea preparation page).
   15 drops of Sangre de Grado, 2 carrots grated and juiced and 30 ml of Cat's Claw/Una de Gato tea and drink in the a.m. daily until hypertension under control.
2) Hemmorhoids:
  Take 120 ml of Cat's Claw/Una de Gato tea daily with 5 drops of Sangre de Grado daily for 8 days then repeat x1.  The Sangre de Drado helps to heal the blood vessels and the Una de Gato takes away the inflammation.

Own Notes:
Upset stomach - My cat had upset stomach with vomiting; she was suffering a lot, in desperation, I mixed 5-8 drops of Dragon's Blood with 1/3 cup of Manayupa tea, she drunk it all and vomiting and convulsion stopped.

I gave few drops of sap mixed with a bit of water to my dog, when she was suffering from diarrhea - excellent result.
