Potential Efficacy of Shiunko for Anti-EGFR Monoclonal Antibody-Induced Skin Fissure: A Single Institutional Case Series.
Okunaka M, et al. Potential Efficacy of Shiunko for Anti-EGFR Monoclonal Antibody-Induced Skin Fissure: A Single Institutional Case Series. Integr Cancer Ther 2024;23.
Study type: Human case series (n=11, oncology) · Added to this library August 23, 2026
What the researchers did
Modern oncology using Shiunko for the painful skin fissures caused by targeted cancer drugs.
What they found
4 of 11 fissures fully healed at 2 weeks and most of the rest improved; no adverse events; patients stayed on their cancer therapy.
Why it matters
A contemporary hospital reaching for the 1617 ointment when modern drugs break the skin — and publishing the result.

Efficacy of Shiunko for the treatment of atopic dermatitis.
Higaki S, et al. Efficacy of Shiunko for the treatment of atopic dermatitis. J Int Med Res 1999;27(3):143-147.
Study type: Small controlled human study
What: Shiunko (the Japanese Purple Cloud Ointment) vs petrolatum vs salt water on atopic dermatitis.
Found: Clinically effective in 4 of 7 Shiunko patients vs 0 of 7 on petrolatum; staphylococcal counts on the skin fell in most Shiunko patients.
Why it matters: Tiny, but the only head-to-head human eczema data for the transitional ointment — and the effect ran through the bacteria, as the "resolve Toxin" function predicts.
The prevention of 2,4-dinitrochlorobenzene-induced inflammation in atopic dermatitis-like skin lesions in BALB/c mice by Jawoongo.
Ku JM, Hong SH, Kim SR, et al. The prevention of 2,4-dinitrochlorobenzene-induced inflammation in atopic dermatitis-like skin lesions in BALB/c mice by Jawoongo. BMC Complement Altern Med 2018;18:215.
Study type: Animal + in vitro
What: Jawoongo (Korea's Purple Cloud Ointment) in the standard chemical-induced eczema mouse model.
Found: Reduced skin thickening and immune-cell infiltration; lowered IgE, IL-4, IL-13, IL-6 and TNF-α; suppressed the MAPK and NF-κB inflammatory machinery.
Why it matters: Three national traditions (China, Japan, Korea) kept the same formula for the same job; the mouse data shows what the job is molecularly.
Lithospermum erythrorhizon Alleviates Atopic Dermatitis-like Skin Lesions by Restoring Immune Balance and Skin Barrier Function in 2,4-Dinitrochlorobenzene-Induced NC/Nga Mice.
Oh J-S, Lee S-J, Choung S-Y. Lithospermum erythrorhizon Alleviates Atopic Dermatitis-like Skin Lesions by Restoring Immune Balance and Skin Barrier Function in 2,4-Dinitrochlorobenzene-Induced NC/Nga Mice. Nutrients 2021;13(9):3209.
Study type: Animal (dose-controlled, vs prednisolone comparator)
What: Zi Cao (Lithospermum) extract tested against the steroid prednisolone in eczema mice.
Found: Matched the steroid on dermatitis scores and beat it on IgE and histamine; rebalanced Th1/Th2; lowered the itch cytokine IL-31 and alarm signal TSLP; raised filaggrin, involucrin, loricrin and the tight-junction proteins.
Why it matters: The "cool Blood, generate flesh" herb rebuilt the entire barrier program while matching a steroid on inflammation — with none of a steroid's thinning.
Oral supplementation of Lithospermum erythrorhizon prevents the development of atopic dermatitis with reducing ceramide degradation in the epidermis of NC/Nga mice.
Kim J, Cho Y. Oral supplementation of Lithospermum erythrorhizon prevents the development of atopic dermatitis with reducing ceramide degradation in the epidermis of NC/Nga mice. Phytother Res 2009;23(9):1250-1256.
Study type: Animal
What: Long-term Zi Cao extract in eczema-prone mice, measuring skin lipids.
Found: Less scratching, lower IgE — and higher epidermal ceramides, because Zi Cao reduced the enzyme that degrades them.
Why it matters: Eczema skin is ceramide-starved. The Blood-nourishing herb literally restocks the lipid mortar between the skin's bricks.
