Two capsules daily with meals is a common manufacturer recommendation

For inflammation: 1-2 capsules daily

For diarrhea support: 1 capsule 3 times daily

Studied range for diarrhea: 125-500 mg daily

Crofelemer (Mytesi prescription): 125 mg twice daily for HIV-associated diarrhea (this is a prescription form, not OTC)

Wound treatment: Apply drops directly to clean wound; allow to dry forming a protective "liquid bandage" film

Insect bites/stings: Apply directly to affected area as needed

Cosmetic/skincare use: Mixed into creams and serums; follow product instructions

Acute conditions: Use as needed until resolution

Ongoing use: Some traditional practices recommend 10 days of use followed by a 1-week break to avoid potential cumulative effects from the taspine content

Long-term safety: Clinical data on continuous long-term use is limited; cycling is a prudent approach for daily internal use

Dosing varies significantly between products due to variations in resin concentration, extract ratios, and processing methods

Always follow manufacturer instructions for the specific product you are using

Start with the lowest effective dose and increase only as needed

For digestive support: Between meals (20 minutes before eating is one traditional recommendation) for systemic absorption, or with meals if it causes stomach sensitivity

For diarrhea: Take at the onset of symptoms and continue as needed throughout the day

For wound healing (topical): Apply as soon as possible after injury for maximum benefit; reapply 1-3 times daily until healed

For general wellness: Morning or split throughout the day

For oral/gum care: After brushing teeth, allow contact with gums for 30-60 seconds before rinsing

Liquid tincture (internal): Traditionally taken between meals; can be diluted in water or juice to mask the bitter, astringent taste

Capsules: With meals is generally recommended to minimize potential stomach sensitivity

Topical applications: Apply to clean, dry skin; no food considerations needed

Clean the wound or affected area with mild soap and water

Pat dry gently

Apply 2-3 drops directly to the wound or rub between fingers first to create a "lather" (the resin will turn from red to a creamy white color when rubbed, indicating activation of its compounds)

Allow to dry completely (forms a protective film)

Can be reapplied 1-3 times daily

For larger wounds, can be applied with a cotton ball

Dragon's Blood liquid is highly astringent and fairly bitter

The bitter taste fades quickly

Dilution in water or juice makes internal use more palatable

The resin will stain fabrics and surfaces, so handle carefully

Topical wound healing: Visible film formation within minutes; healing acceleration becomes apparent over several days

Diarrhea relief: May begin to work within hours; full effects typically within 24-48 hours

Antimicrobial effects: Immediate upon topical contact; systemic effects develop over days of consistent use

Anti-inflammatory effects: Topical relief often within minutes to hours; systemic benefits develop over weeks

Gastric healing: Animal studies showed significant improvement within 7 days of daily use

Chloride channel inhibition (diarrhea relief): The proanthocyanidin oligomers (crofelemer/SP-303) block both the CFTR (cystic fibrosis transmembrane conductance regulator) and calcium-activated chloride channels in intestinal cells; this dual blockade reduces the excessive fluid and chloride secretion that causes watery diarrhea, without affecting normal intestinal motility

Fibroblast chemotaxis (wound healing): Taspine acts as a chemotactic factor that attracts fibroblasts to the wound site, where they produce collagen and rebuild damaged tissue; this is the same fundamental mechanism the body uses naturally, but Dragon's Blood accelerates it

Astringent protein binding: The high tannin and proanthocyanidin content causes proteins to coagulate and contract at the application site, creating a temporary protective seal over wounds and reducing capillary bleeding

Antimicrobial activity: The combination of proanthocyanidins, tannins, and alkaloids disrupts bacterial cell walls and inhibits microbial protein synthesis; effective against both Gram-positive and Gram-negative bacteria

Antiviral mechanism: Taspine and certain proanthocyanidins interfere with viral entry and replication, particularly for enveloped viruses like herpes simplex

Anti-inflammatory action: Inhibits the production of inflammatory mediators, blocks neurogenic inflammation pathways, and modulates complement system activity

Antioxidant protection: Proanthocyanidins directly scavenge free radicals and protect cells from oxidative damage

Immunomodulation: Inhibits T-cell proliferation and modulates complement pathways, suggesting potential benefit in autoimmune-related conditions

When applied topically and rubbed between the fingers, the red resin turns creamy white

This color change indicates the resin's active compounds are dispersing and ready to work
