“…Triphala is an anti-inflammatory agent. [15] Nimba has antimicrobial [16] property that may be helpful in shedding off the scales of the skin and preventing secondary infection. It is helpful in the Pachana (metabolism) of Ama Visha (toxins) and corrects vitiated Rasa Dhatu in the body.…”

Skin being the largest and a protective covering of all our internal organs is susceptible to many harmful environmental factors causing different kinds of bacterial, viral and fungal infections. All the skin disease in Ayurveda has been classified into Mahakushtha and Kshudra Kushtha. Dadru is one among them. As per modern perspective “Superficial fungal infection of skin” is the most common dermatological manifestation affecting up to 15% of world‟s population in all age groups. In present time, antifungal treatment is based on systemic and topical medications which may lead to many side effects and relapse too. Fungal infections are more demoralizing to the patients due to their appearance, recurrence, chronicity, and negative psychological impact. Keeping this fact in mind below mentioned study drafted to focuses on Ayurvedic Shamana and Shodhan Chikitsa in Dadru Kushtha. AIM AND OBJECTIVES –To evaluate the effect of Shodhana and Shamana Chikitsa in Dadru Kushtha. MATERIAL AND METHODS- It will be collected from classical Ayurvedic texts as well from previous research works / thesis, Internet sources, research articles and modern sciences text. DISSCUSSION AND CONCLUSIONS- On the basis of signs and symptoms we can correlated the Dadru Kushtha to Tinea Cruris. In This case report, a 67 yr old male patient came with complaints of Dadru Kushtha, which is closely similar to the presentation of Tinea Cruris infection. The present case showed significant improvement with Ayurvedic Shodhan, Shaman and Bahiparimarjan (topical) Chikitsa in Dadru.

“…During the period of infection with CWR, the pale-green to yellow white rust spots are found on the upper surface of the leaf. Centre of the spots turns brown and necrotic upon aging (Kumar et al, 2021). The disease caused degradation of flower quality and resulted in up to 100% yield loss, thus causing destructive damage (Bety and Pangestuti, 2021).…”

Chrysanthemum White Rust (CWR) caused by Puccinia horiana Henn. is a major disease in the production process of chrysanthemum, which is widely spread all over the world and can be called “cancer” of chrysanthemum. To clarify the disease resistance function of disease resistance genes can provide a theoretical basis for the utilization and genetic improvement of chrysanthemum resistant varieties. In this study, the resistant cultivar ‘China Red’ was used as the experimental material. We constructed the silencing vector pTRV2-CmWRKY15-1 and obtained the silenced line named TRV-CmWRKY15-1. The results of enzyme activity after inoculation with pathogenic fungi showed that the activities of antioxidant enzymes SOD, POD, CAT and defense-related enzymes PAL and CHI in leaves were stimulated under the stress of P. horiana. In the WT, the activities of SOD, POD and CAT at the peak value were 1.99 times, 2.84 times and 1.39 times higher than that in TRV-CmWRKY15-1, respectively. And the activities of PALand CHI at the peak were 1.63 times and 1.12 times of TRV-CmWRKY15-1. The content of MDA and soluble sugar also confirmed that chrysanthemum was more susceptible to pathogenic fungi when CmWRKY15-1 was silenced. The expression levels of POD, SOD, PAL and CHI at different time points showed that the expressions of defense enzyme related genes were inhibited in TRV-WRKY15-1 under the infection of P. horiana, which weakened the ability of chrysanthemum to resist white rust. In conclusion, CmWRKY15-1 may increased the resistance of chrysanthemum to white rust by increasing the activity of protective enzyme system, which laid a foundation for breeding new varieties with disease resistance.
