By Tradition
Karappan is the most common Siddha skin disease diagnosis — chronic, itchy, oozing skin condition. Classified under Kushta Rogam (skin diseases). Attributed to all three Kutram (humors) affecting the skin.
Treatments (1)
மஞ்சள் (Manjal) — Curcuma longa / Turmeric
Manjal (turmeric) is central to Siddha dermatology. Used both internally and externally for Karappan (eczema) and other skin diseases. The Siddha tradition pioneered turmeric paste (Manjal Poosi) application for skin conditions.

Manjal (Curcuma longa) in Siddha dermatology: clinical audit of Karappan treatment
Combined internal (Manjal Chooranam) and external (Manjal Poosi) turmeric treatment showed marked improvement in 74% of Karappan patients at 6 weeks. Itching (Aripphu) resolved fastest, followed by oozing and discoloration.
Curcumin plus topical turmeric paste for chronic eczema: randomized factorial design trial
The combined internal-external group (Siddha approach) showed significantly better SCORAD improvement than either monotherapy alone (p=0.01). Internal-only curcumin reduced inflammatory markers; external paste improved local skin symptoms. Synergistic interaction confirmed.
Egyptian medicine had detailed descriptions of skin conditions. Aloe, honey, and myrrh were primary skin remedies. The Ebers Papyrus contains entire sections devoted to skin diseases and cosmetic dermatology.
Treatments (3)
'Rw (ארו / Eru) — Aloe
Aloe was highly valued in Egyptian medicine, used since at least 1550 BCE (Ebers Papyrus). Cleopatra reportedly used aloe for skin care. Used for wounds, burns, skin conditions, and as a purgative.

Ebers Papyrus — Skin and Wound Sections
Aloe ('rw) prescribed for skin conditions, burns, and wounds. One of the earliest documented medicinal uses of aloe — approximately 3500 years of continuous use.
Commiphora myrrh extract for wound healing: randomized controlled comparison with standard care
Myrrh extract significantly accelerated wound closure and reduced infection rates compared to standard wound care. Sesquiterpene-mediated anti-inflammatory and antimicrobial activity confirmed.
Skin conditions treated with goldenseal (Eastern Woodland), echinacea (Plains), and regional plant poultices. Goldenseal (Hydrastis canadensis) was the premier Cherokee skin and wound medicine.
Treatments (1)
Tsi Yu Gi (Cherokee) / Goldenseal — Hydrastis canadensis
Goldenseal was the premier wound and infection medicine of the Cherokee and Iroquois. The bright yellow root (due to berberine) was used for skin infections, digestive complaints, and eye infections. Now one of the most commercially important Native American medicinal plants.

Berberine (from Hydrastis canadensis) for skin infections: randomized controlled trial
Topical berberine preparation showed comparable efficacy to standard antiseptic for superficial skin infections. Berberine's mechanism: direct DNA intercalation in bacteria and inhibition of FtsZ protein (cell division).
Berberine-containing plants for dermatological conditions: systematic review
Berberine-containing preparations showed consistent antimicrobial activity against Staphylococcus aureus, Candida albicans, and dermatophytes in vitro. Clinical evidence strongest for acne and superficial fungal infections. Goldenseal-specific clinical trials remain scarce.
Skin conditions treated with Ti plant (Cordyline), turmeric (in tropical Polynesia), and various endemic plants. Noni (Morinda citrifolia) is the premier Polynesian skin remedy in tropical island groups.
Treatments (2)
Noni (pan-Polynesian) — Morinda citrifolia
Noni is one of the most versatile Polynesian medicinal plants, used across the Pacific for inflammation, skin conditions, pain, and as an immune tonic. The fruit, leaves, and root are all used medicinally. Hawaiian name: Noni. Samoan: Nonu.

Kī / Ti (Hawaiian) / Tī (Māori) — Cordyline fruticosa
The Ti plant was carried by Polynesian voyagers across the Pacific as a sacred and medicinal plant. Leaves used for wrapping, healing, and ritual protection. The leaf is believed to ward off negative spiritual influences.

Traditional Polynesian wound management: Ti plant (Cordyline fruticosa) leaf dressings in rural Pacific Island clinics
Ti leaf wraps changed daily showed comparable healing outcomes to standard gauze dressings for superficial tropical wounds. Infection rates were similar between groups. Ti leaf availability and cost advantage makes it a practical wound management option in resource-limited Pacific settings.
Morinda citrifolia (Noni) for dermatological conditions: systematic review of traditional use and clinical evidence
Noni demonstrated consistent antimicrobial and wound-healing activity in preclinical models. Clinical evidence limited to small observational studies. Scopoletin, alizarin, and anthraquinones identified as key dermatological actives. Topical application (leaf poultice) better supported than oral juice for skin conditions.
Vicharchika is classified under Kshudra Kushtha (minor skin diseases) in Ayurveda. Characterized by itchy, oozing, discolored skin patches. Caused by vitiation of all three doshas affecting Rakta and Mamsa Dhatus.
Treatments (1)
हरिद्रा (Haridra) — Curcuma longa / Turmeric
Haridra is one of the most important Ayurvedic medicinals. Potent Shothahara, Krimighna, and Varnya. Tridoshahara — balances all three doshas.

Kampo approaches skin disease through the Ki-Ketsu-Sui framework. Most chronic skin conditions involve Oketsu (blood stasis) and/or heat in the blood. Abdominal findings guide formula selection.
Treatments (1)
桂枝茯苓丸 (Keishi-Bukuryō-Gan) — Cinnamon Twig and Poria Pill
Classical Oketsu (blood stasis) formula from the Jin Gui Yao Lue. The most commonly prescribed blood-stasis-resolving formula in Kampo. Widely used for inflammatory conditions, skin disease, and cardiovascular complaints.

Skin conditions including rashes, fungal infections, and chronic dermatitis. African Potato and Aloe are widely used for skin conditions. Skin disease may indicate internal blood impurity or spiritual contamination.

Aloe vera gel significantly accelerated wound healing, reduced burn pain, and improved outcomes in various dermatological conditions. Acemannan identified as key immunomodulatory and wound-healing compound.
Hypoxis hemerocallidea for atopic dermatitis: randomized placebo-controlled pilot study
No significant improvement in SCORAD scores at 8 weeks compared to placebo (p=0.23). Itch VAS improved modestly (p=0.06). Rooperol plasma levels were low, suggesting possible bioavailability issues with the oral formulation.
