RESUMEN
Kamala fruit (Mallotus philippensis), hereinafter MP, has been simultaneously exercised for the extraction of a natural dye, C.I. orange and its peels were converted into an efficient adsorbent for the rapid removal of methylene blue (MB) dye from aqueous solutions. The material has been characterized by Fourier Transform Infra-red (FTIR),Field Emission Scanning Electron Microscopy- Electron dispersive spectroscopy (FESEM-EDS), Brunauer-Emmett-Teller (BET) surface area, and pHZPC. FTIR suggests the presence of polyphenolic moieties responsible for adsorption, whereas FESEM confirms the porous texture. Optimization of process variables such as contact time, pH, adsorbent dose, and temperature of operation indicates that the adsorption gets modulated by the pH, with a best at 11. The Freundlich model (R2 = 0.994), and pseudo-second-order kinetics (R2 = 0.999) best describe the adsorption pathway. Dilute hydrochloric acid is sufficient to induce >66% regeneration, which ensures reusability. With the maximal uptake for MB is 30.2 mg/g at ambient conditions, the superiority over the existing materials has been confirmed. Treatment of dye containing industrial effluent suggests about a 50% reduction in one cycle. It can be concluded that both-way benefits, namely natural dye extraction and preparation of a peel-based adsorbent for methylene blue removal from aqueous solution, can be achieved using the kamala fruit peels.
Mallotus philippensis, a seasonal fruit, commonly known as Kamala, was employed to serve a dual advantage of extracting a natural dye called C.I. orange from the peels; thereinafter, the peels were converted as an adsorbent to remove Methylene blue from water and industrial wastewater with high efficacy. From 100 g of raw material, 1.7 g of C.I. orange dye was extracted, along with 44 g of peel-based adsorbent. The maximum adsorption capacity for MB is 30.2 mg/g at ambient conditions, better and more impactful than contemporary adsorbents. The approach is firmly established in the circular economy as a dual benefit agent, generating clean and green revenue through natural dye extraction.

Hepatitis B is one of the most common causes of liver disease, and due to unawareness of the safety measures, more prone to spread. As per the World Health Organization, for the South East Asia region, its prevalence is 2%. Yellowish discoloration of the eyes, body, and urine, abdominal discomfort, and vomiting is its cardinal symptoms. In Ayurveda, this set of symptoms is known as Kamala. This case report illustrates the effectiveness of the Ayurveda treatment modality in a patient with a viral load of 3705.71 IU/ml, and the values of AST (aspartate aminotransferase) and alanine transaminase (ALT) were 140 IU/ml and 173 IU/ml, respectively. A 40-year-old female patient with a complaint of yellowish discoloration of urine, eyes, and skin with fatigue and irritability was diagnosed with Ubhayapatha Ashrita Swatantra Kamala. The patient was treated with Ayurveda drugs and Virechana Karma (therapeutic purgation). After the treatment for 13 months, the disease was cured. Improvement was observed based on hepatitis B virus deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) (hepatitis B DNA PCR) (decreased from 3705.71 IU/ml to <50.0 IU/ml) and the values of AST (decreased from 140 IU/ml to 19.0 IU/ml) and ALT (decreased from 173 IU/ml to 28 IU/ml). The patient was stable and asymptomatic during the follow-up period of 4 months.
RESUMEN
Neonatal hyperbilirubinemia is the elevation of the bilirubin level in the newborns blood, which results in yellowish staining of the skin and sclera of the newborn eyes by pigment of bile. It is due to the breakdown of RBC's (which release bilirubin into the blood) and the immaturity of newborns liver (which cannot effectively metabolize the bilirubin and prepare it for excretion into the urine). Increased bilirubin production, reduced hepatic clearance and enhanced enterohepatic circulation are the sole causes of increased prevalence of jaundice in newborn. The science of Ayurveda is supposed to add a step in order to understand the pathophysiology of neonatal jaundice that have resemblance with clinical entity of kamala (jaundice) mentioned in Kashyapa Samhita. The concept of neonatal hyperbilirubinemia in Ayurveda can be understood in the context of Pittaja stanya dushti along with the physiological variations in the newborns leading to the raised level of unconjugated bilirubin. Therefore, the patho-physiology should be known by a pediatrician in Ayurveda based on the involvement of dosha, dhatu, mala and srotas. Hence, an attempt is made in this review to discuss about the hidden concept of pathology of neonatal jaundice described in Ayurveda. These findings to understand the concept of neonatal jaundice in Ayurveda add up to the Ayurvedic science that has been developed through ages.
RESUMEN
Vasaguduchyadi Kwatha is a compound Ayurvedic formulation, indicated for the treatment of liver diseases, especially for Kamala (jaundice) and Panduroga (anemia). However, till date, no safety profile of this formulation has been reported; hence, in the present study, freshly prepared and market samples of Vasaguduchyadi Kwatha were evaluated for acute toxicity. Acute toxicity test was evaluated as per OECD 425 guidelines with 5 000 mg/kg as limit test in Wistar strain albino rats. Test formulations were administered to overnight fasted animals and parameters like body weight, behavioral changes, and mortality were assessed for 14 days. Hematological and biochemical parameters were assessed on 14(th) day. Results showed no significant changes in terms of behavioral changes, mortality, and body weight. Both the samples did not affect any of the hematological parameters. However, increase in blood urea level was observed. This study shows that both the samples of Vasaguduchyadi Kwatha are relatively safe up to the dose of 5 g/kg. However, further chronic toxicity evaluation is necessary to establish its safety profile on chronic administration.
RESUMEN
Thalassemia is the commonest single gene disorder in India. About 10,000 infants with Thalassemia major are born every year. The present study was under taken with a hope to prevail better quality of life to the Thalassemic patients. Pallor being the chief complaint, a randomized controlled trial was undertaken with Dhatri Avaleha as it is specially mentioned for Pandu, Kamala & Haleemaka Roga. Children between age group of 1 to 15 years were randomly divided in two groups: Drug treated group (Group A) and Control group (Group B). Assessment was done on subjective and objective parameters after 30 and 60 days of treatment with follow up of two month. Statistically significant (P<0.01) result was obtained in Blood transfusion interval in group 'A' in comparison to group 'B'. Dhatri Avaleha may have a potential to increase blood transfusion interval and decrease secondary infection and thus it can be used as supportive therapy with modern medical management.
