A Case of Morvan's Syndrome Associated with Heavy Metal Poisoning after Ayurvedic Drug Intake.

Morvan's syndrome is an autoimmune disorder of peripheral and central nervous system mediated by VGKC antibody. Here we report a case of Morvans syndrome who presented 1 month after ayurvedic drug intake. She presented with symptoms of peripheral nerve hyperexcitablity and autoimmune testing revealed positive result for VGKC antibody. Heavy metals level was also significantly raised. She improved after a course of steroids. This case report tries to highlight the association of VGKC mediated Morvans syndrome with heavy metal poisoning and its incidental occurence after Ayurvedic drug intake.

Characterization and Antimicrobial Property of Some Heavy Metals Containing Ayurvedic Drugs.

Ayurvedic medicines are often used in different formulations, the heavy metals, which are generally referred to as being toxic. In this work, we report on the physicochemical characterization and biological activity of some typical Ayurvedic drugs available in the market that contain arsenic, mercury and lead with the emphasis on their antibacterial performance. Among the formulations studied, some of the drugs with 'amorphous' texture (and higher solubility) were found quite active against some bacterial strains whereas the formulations possessing crystalline texture (and low solubility) were found practically ineffective. The moderate activity of some drugs against Gram-negative bacteria fairly suggested the presence of the small-sized polar molecules which was also supported by the FTIR spectroscopic data.

How Harmful Can Herbal Remedies Be? A Case of Severe Acute Tubulointerstitial Nephritis.

Acute interstitial nephritis (AIN) is a condition in which acute kidney injury (AKI) is characterized by the histological finding of interstitial inflammation. Hyponidd is an ayurvedic drug containing Momordica charantia, Gymnema sylvestre, Swertia chirata, etc., used for the treatment of Type 2 diabetes mellitus (DM) and polycystic ovarian disease as an insulin sensitizer. There are no case reports of AIN caused by this drug yet. We report a biopsy-proven case of AKI due to severe AIN associated with the use of hyponidd tablet in a 60-year-old male with DM and hypertension. As these types of various indigenous compounds are used as home remedies in our country, awareness about the possible adverse effects of these agents among physicians is very important in the early diagnosis and management.

A Metallurgical Study of Naga Bhasma.

BACKGROUND: The metal Naga (Lead) is being used by Indians since ancient times. Its external and internal uses have been described in Caraka, Susruta and other Ayurvedic Samhita. According to most of the Rasa texts, Naga Bhasma and its formulations are used in many diseases such as Prameha, Jvara, Gulma, Sukrameha etc. OBJECTIVES: In the present study, Naga Bhasma was prepared by the traditional Puta method (TPM) and by the electric muffle furnace Puta method (EMFPM) and standardized using Metallographic studies. Doing so helps in the study of the microstructure of Naga Bhasma and also helps in the identification of the metal particles along with the nature of compound formed during the Marana (Bhasmikarana) process. SETTING AND DESIGN: Different samples from initial raw material to final product of Naga Bhasma were collected during the pharmaceutical process (1st, 30th and 60thPuta) from both methods i.e. TPM and EMFPM. Samples from both methods were studied using metallographic examination. MATERIALS AND METHODS: The processing of the Naga Bhasma (sastiputa) was done according to Ananda Kanda[9] Samples from the raw material i.e. Asodhita Naga (raw Lead) and that processed after 1st, 30th and 60th Puta from both methods i.e. traditional Puta method (using heat from burning of cow dung cakes) and electric muffle furnace Puta method were taken. They were mounted on self hardening acrylic base. After careful polishing to obtain scratch free surface of product, they were used for metallurgical study. CONCLUSION: This study shows that traditional Puta method may be better than electric muffle furnace Puta method because of more homogeneous distribution of Lead sulphide in the Naga Bhasma which is prepared by traditional method.

Development of Ayurveda - Tradition to trend.

ETHNOPHARMACOLOGICAL RELEVANCE: Ayurveda entails a scientific tradition of harmonious living and its origin can be traced from ancient knowledge in Rigveda and Atharvaveda. Ayurveda is a traditional healthcare system of Indian medicine since ancient times. Several Ayurvedic medicines have been exploiting for treatment and management of various diseases in human beings. The several drugs have been developed and practiced from Ayurveda since ancient time to modern practice as 'tradition to trend'. The potential of Ayurvedic medicine needs to be explored further with modern scientific validation approaches for better therapeutic leads. AIM OF THE STUDY: The present study was aimed to explore the various aspects of Ayurveda and inspired drug discovery approaches for its promotion and development. MATERIALS AND METHODS: We have reviewed all the literature related to the history and application of Ayurvedic herbs. Various aspects for the quality control, standardization, chemo-profiling, and metabolite fingerprinting for quality evaluation of Ayurvedic drugs. The development of Ayurvedic drugs is gaining momentum with the perspectives of safety, efficacy and quality for promotion and management of human health. Scientific documentation, process validation and several others significant parameters are key points, which can ensure the quality, safety and effectiveness of Ayurvedic drugs. RESULTS: The present review highlights on the major goal of Ayurveda and their significant role in healthcare system. Ayurveda deals with several classical formulations including arka, asavas, aristas, churna, taila, vati, gutika, bhasma etc. There are several lead molecules that have been developed from the Ayurvedic herbs, which have various significant therapeutic activities. Chemo-profiling of Ayurvedic drug is essential in order to assess the quality of products. It deals with bioactive compound quantification, spurious and allied drug determination, chromatographic fingerprinting, standardization, stability and quality consistency of Ayurvedic products. CONCLUSIONS: Scientific validation and the documentation of Ayurvedic drugs are very essential for its quality evaluation and global acceptance. Therapeutic efficacy of Ayurvedic herbs may be enhanced with high quality, which can be achieved by identity, purity, safety, drug content, physical and biological properties. Ayurvedic medicines need be explored with the modern scientific approaches for its validation. Therefore, an attempt has been made in the present review to highlight the crucial aspects that need to be considered for the promotion and development of Ayurvedic medicine.

Investigating structural aspects to understand the putative/claimed non-toxicity of the Hg-based Ayurvedic drug Rasasindura using XAFS.

XANES- and EXAFS-based analysis of the Ayurvedic Hg-based nano-drug Rasasindura has been performed to seek evidence of its non-toxicity. Rasasindura is determined to be composed of single-phase α-HgS nanoparticles (size ∼24 nm), free of Hg(0) or organic molecules; its structure is determined to be robust (<3% defects). The non-existence of Hg(0) implies the absence of Hg-based toxicity and establishes that chemical form, rather than content of heavy metals, is the correct parameter for evaluating the toxicity in these drugs. The stable α-HgS form (strong Hg-S covalent bond and robust particle character) ensures the integrity of the drug during delivery and prevention of its reduction to Hg(0) within the human body. Further, these comparative studies establish that structural parameters (size dispersion, coordination configuration) are better controlled in Rasasindura. This places the Ayurvedic synthesis method on par with contemporary techniques of nanoparticle synthesis.

Adverse reaction of Parasika Yavani (Hyoscyamus niger Linn): Two case study reports.

Adverse drug reaction (ADR) is an unpleasant reaction related to the use of medicine at its therapeutic dose. Ayurveda is well aware of such adverse reactions. Parasika Yavani (Hyoscyamus niger Linn.) is an Ayurvedic drug effectively used in many psychological disorders, if not used judiciously it causes adverse reactions. In present study two cases of ADR on the usage of Parasika Yavani are reported. Churna in capsule form given in different dosage forms (500 mg once a day, 250 mg twice a day, 250 mg once a day) in Chittodwega (generalised anxiety disorder). 500mg capsule was given to many patients in the study, but no adverse reactions were noticed except in above given two cases. So, in these two cases, the dose was tapered down to 250 mg twice a day, and then to 250 mg once a day to avert the adverse reactions and to fix the therapeutic dose in such individuals (250 mg once a day). On analysis, these two individuals were found to be of Pitta Prakriti. Parasika Yavani is found to increase Pitta and triggers the establishment of ADRs. So, while administering therapeutic dosage, a physician should be vigilant. In the current study, it is observed that 500 mg of Parasika Yavani powder in Pitta Prakriti individuals triggered ADRs while 250 mg once a day was safe. It was also observed that Kapha and Vata Prakriti, patients did not develop any adverse reactions.

Synthesis, characterization and histopathological study of a lead-based Indian traditional drug: naga bhasma.

The aim of the present study is to prepare and characterize Naga bhasma on structural and elemental basis to address the role of the raw materials used during the preparation, compound form of the lead bhasma, nature (crystalline/amorphous) and crystallite/particle size of the drug. The study also covers the toxicological effect of the drug on albino rats. It was found that drug contains lead in nano-crystalline (~60 nm) lead sulfide form (Pb(2+)) associated with the organic contents and different nutrient elements coming from the herbs used during the preparation. Naga bhasma prepared was found to be totally safe in histopathology study on rats at a dose of 6 mg/100 g/day. The different characterization techniques used present a role model for the quality control and standardization of such kinds of herbo-metallic medicines.

A survey of the labeling information provided for ayurvedic drugs marketed in India.

BACKGROUND: Ayurvedic drugs fall under the purview of the Drugs and Cosmetics Act, 1940 and labels on Ayurvedic drug containers need to comply with the requirements specified in this Act (Part XVII, 161). The present survey was conducted to evaluate whether Ayurvedic drug labels were in compliance with the Drugs and Cosmetics Act, 1940 with respect to their contents. MATERIALS AND METHODS: Ayurvedic drugs container labels at three Ayurvedic pharmacies were selected based on the convenience sampling method. Their contents were checked against a set of quality criteria given in the Act. The results are expressed as percentages. RESULTS: Basic manufacturing details were present on all the 190 labels reviewed (101 classical and 89 proprietary formulations). References from authoritative books as specified in the 1st Schedule of the Act were mentioned on 90% of labels of the 101 classical formulations reviewed. Fifty-five percent (n = 56) labels of classical drugs and 79 (88%) labels of proprietary drugs provided an ingredient list. Although 20 (20%) of classical formulations and 13 (15%) of proprietary formulations labels mentioned the Cautions/Warnings, only one language (either English or Hindi) was used. CONCLUSION: Ayurvedic drug container labels were not compliant with most of the requirements specified in the Act.
