Previous studies of the proanthocyanidin compound, isolated from the latex of the Croton Lecheri plant (Dragon’s blood) have confirmed the suppression of a wide range laboratory-grown viruses. The product is not registered as a dietary supplement or medicament, but many studies and traditional uses are focused on oral consumption and health care.

The recommended daily dose is 5-10 drops diluted in 10 ml of water. It may taste unpleasant to some, so the easiest application is to use brandy cups, or add drops to cold tea.

We already know that the corona behaves similarly to the flu, and an organism with a stronger immunity system is more likely to defend itself against the virus.

Ubillas, R. et al.  highlights the importance of a compound called SP-303, an oligomer of a blue plant pigment named proanthocyanidin, isolated from the latex of the plant species Croton lechleri ​​(Eupborbiaceae), commonly known as Dragon’s Blood. Their discovery was published in The International Journal of Phytotherapy and Phytopharmacology. Isolated oligomers have shown broad activity against a variety of DNA and RNA viruses  such as: respiratory syncytial virus (RSV), influenza A virus (FLU-A), and parainfluenza virus (PIV). SP-303 also has shown significant inhibitory effects against herpes virus (HSV) type 1 and 2, including acyclovir and foscarnet resistant virus. Inhibition was also observed against hepatitis A and B viruses.

The anti-viral mechanism of SP-303 appears to arise from its direct attachment to the components of the viral envelope, which results in the prevention of viral binding in the body and penetration through the membrane.

Testing has shown best results applying SP-303 as follows: local application to skin lesions, aerosol inhalation to treat influenza infection, and oral dosage to control respiratory syncytial virus and flu virus.
