MADONMADA DIFFERENTIAL DIAGNOSIS: A COMPREHENSIVE REVIEW

Introduction: Madonmada is a disease with distinct manifestations. Manodukhaja, Adija, and Chittaja Unmada are particular types of Unmada, as per different treatises. More knowledge is needed regarding their similarity to Madonmada. Hence, this study has been undertaken to review and analyse the same. Methodology: A detailed study of Madonmada and different types of Unmada was done using various Ayurvedic treatises, and findings were noted. Results: Manodukhaja, Adija, and Chittaja Unmada differ in their aetiology, pathogenesis, symptoms, and prognosis from Madonmada. Hence, they are separate manifestations. Discussion: Manodukhaja Unmada, compared to Madonmada, has two different nidanas; it does not share a similar pathogenesis and 2 out of 14 lakshanas match. Adija unmada of Astanga Sangraha and Chittaja Unmada of Astanga Hridaya both differ in etiology, pathophysiology and symptoms from that of Madonmada, where 6 out of 14 symptoms are similar. Hence, Madonmada can be considered as a separate disease manifestation.

A RANDOMISED CLINICAL TRIAL TO EVALUATE THE EFFICACY OF VARMAN THERAPY IN THE MANAGEMENT OF VISHADA WITH SPECIAL REFERENCE TO GENERALISED ANXIETY DISORDER

Vishada has not been described as an individual clinical disease in Ayurvedic treatises, but references to Vi-shada are scattered in the classics. Primary psychological conditions caused purely by manas Doshas, i.e., Ra-jas and Tamas, include Kama, Krodha, Lobha, Moha, Baya, Irshya, Vishada etc. Vishada, by its symptomatol-ogy, shows much more similarity to the symptoms of generalised anxiety disorder. Varmam refers to the vital point present all over the body. According to the siddha system of medicine, when pressure is given on these Varmam points under control for a specific time and duration, it cures several diseases. MATERIAL AND METHOD: A randomised, open, standard, controlled, clinical, interventional trial on 30 hu-man subjects. Patients were divided into two groups, one with Varmam therapy with Ksheerabala Tailam appli-cation and the other with only Varmam therapy. The total duration of treatment is 35 days. There are two fol-low-ups every 7th day. There are 28 Varmam points located in the region from the top of the head to the neck, of which 10 are used in the study to manage Vishada. RESULTS—After assessing the parameters of assessment criteria after treatment and inter-group comparison, it revealed that there was a significant effect of therapy in the patients of Vishada, and group B had a better im-pact than group A, which includes the Varmam stimulation along with Ksheerbala Tailam. CONCLUSION – Varmam therapy is effective in the management of Vishada w.s.r to Generalized anxiety dis-order.

UNDERSTANDING OF AVARANA W.S.R TO KAPHAVRUTA AND MEDHASAVRUTHA VATA IN THE PATHOGENESIS OF PAKSHAGATHA

Avarana is a unique concept in Ayurveda. Avarana is the path along which the pathogenesis of many diseases’ proceeds. There are many conditions which mimic Avarana. It is either unnamed or least diagnosed due to lack of knowledge. Pakshagatha, one among the Vatajananatmaja vikara, is considered Vatavyadhi or Mahavatavyadhi. It can either be due to kevala vataja, dosha samsrusta/margavarana or datukshayajanya. As the treatment principle is different for different types of pakshagatha, it is essential to understand the various types of pakshagatha. Pakshagatha can be correlated to monoplegia, hemiplegia, paraplegia, and quadriplegia, which result after stroke or CVA. Many kinds of Avarana vata are mentioned in Ayurvedic treatises based on Avruta and Avaraka. The present article attempts to understand the role of kaphavruta and medasavruta vata in the pathogenesis of pakshagatha.

Literary review on Dhoopana Karma quoted in various ayurvedic classics for the management of pain and inflammation

ABSTRACT Dhoopana Karma (fumigation therapy) is mentioned in various scriptures of Ayurveda as Rakshoghna Karma (protective action) to prevent and cure diseases. It is less practiced for pain management in Ayurveda, whereas it is widely practiced in the Chinese Medicine System. Dhoopana Karma can be used effectively when there is involvement of Kapha Dosha along with Vata Dosha, where Kleda (discharge) is more. But in Ayurvedic classics, we get very few references regarding Dhoopana Karma as Chikitsa for Shoola (pain). Sukshma Srotogamitva (subtle channel penetration) of Dhoopana Dravya (fumigating substance) is due to Akasha, Vayu, and Agni Mahabhoota. Hence, they possess properties like Kledaghna (reduces discharge), Shoolaghna (pain-alleviating), Vranaropaka (wound-healing), and Shothahara (anti-inflammatory), etc. Dhoopana Karma also improves blood circulation, which helps to reduce pain and inflammation. In this article, an attempt is made to understand the anti-inflammatory action of Dhoopana Karma mentioned in various Ayurvedic treatises. Key words: Dhoopana, Shoolahara, Shothahara, Pain and inflammation.

Fundamental Tenets of Personal Hygiene in Ayurveda

Certain concepts of personal cleanliness and health promotion are described in the ancient Indian medical system known as Ayurveda. These concepts are explained in Ayurvedic treatises using their own terminology. The ideas and precepts included in the traditional Ayurvedic writings can be categorized into two groups: Dinacarya, or daily regimens, and Ratricarya, or daily regimens, particularly at night. Together, these two provide information on maintaining personal hygiene and promoting health. Since Ayurveda does not clearly distinguish between promoting health and maintaining hygiene, the concepts may be interpreted in light of their intended use. This paper attempts to compile some of the most significant ideas about personal hygiene and health promotion found in traditional Ayurvedic treatises.

Doota adhyaya of Bhela indriya sthana - An explorative study

‘Maharshi Bhela’ belongs to samhita period (100 BC - 400 BC) and he has composed an Ayurvedic treatise known as ‘Bhela samhita’. Bhela samhita is divided in to 8 sections and 120 chapters. Indriya sthana is one among the 8 sections of ‘Bhela samhita’ and it comprised of 12 chapters. Like ‘Indriya sthanas’ of other ancient Ayurvedic texts, ‘Bhela indriya sthana’ also deals with arishta lakshanas (fatal signs and symptoms) and other prognostic aspects. ‘Doota adhyaya’ is the 8th chapter of ‘Bhela indriya sthana’ which comprises of 16 verses dealing with estimation of prognosis based on the characteristic features of caregiver (doota). Estimating prognosis based on the phenotypic characteristics of caregiver is the unique contribution of Ayurveda and ‘Maharshi Bhela’ has allotted a separate chapter for this in ‘Indriya sthana’ (doota adhyaya). The contents of ‘doota adhyaya’ are unique and needs further in-depth exploration. Previous works conducted on ‘Charaka indriya sthana’ and ‘Bhela indriya sthana’ have explored various neglected concepts having prognostic importance. Studies on ‘Doota adhyaya’ of ‘Bhela indriya sthana’ have been lacking and the present study is aimed to explore the contents of this chapter in terms of their prognostic significance. Thousands of years ago, ‘Maharshi Bhela’ has identified and documented concepts like caregiver burden & distress, factors determining the impact of caregiving on caregivers, desirable or positive personality characteristics of a caregiver and their influence on prognosis and role and impact of geographical, cultural, economic, social and personality characteristics of a caregiver on caregiving and prognosis of a disease condition of the patient or care recipient. Concepts of ‘Jyotishya shastra’ (astrology) and ‘Nimitta’ or ‘Shakuna shastra (astrology of omens)’ were also incorporated in assessing the prognosis. Further works are required to establish the facts mentioned in this chapter.

ROLE OF HERBOMINERAL DRUGS IN THE MANAGEMENT OF COMPLICATIONS OF STHAULYA- A CRITICAL REVIEW

In Ayurvedic treatise Caraka Samhita Acharya Caraka has classified Atisthaulya under the eight most con-demnable (Ashtanindita) conditions of the society and considered it under Santarpanotha Vikaras (diseases due to excessive nutrition). Further Acharya explains that if skinny and obese both persons who are equally equipped suffer from a particular disease then that disease afflicts the obese person more severely than the skinny. Cakrapani, explaining it says that in the obese saturation further aggravates obesity while desaturation because of increased digestive fire is not tolerated by the patient, thus the condition becomes difficult to manage. In obese person fat is nourished more than the other Dhatus because it is extensively spread all over the body and takes all the nourishment overcoming other Dhatus causing Medas Sanchaya. Disproportionately increased Medas (fat/ adipose tissue) and Mamsa Dhatu (muscle tissue) causes obstruction of Medovaha Srotas due to which Aahara Rasa does not reach the other Dhatus and thus nourishes the Medas only resulting in Atisthaulya. As it is said that 'Vayordhatu Kshayat Kopo Margasya Aavaranena Ch' therefore due to Avaran of Medovaha strotas Vayu is excessively aggravated and as such stimulates Jatharagni causing quick digestion of consumed food and leaving the person yearning for more food. Ayurvedic classical texts describe a detailed treatment reg-imen for Sthaulya and its complications. In this regard Aushadh Dravyas which are Strotoshodhak heavy and desaturating should be given. This includes Lekhaniya, Medohara, Guru, Aptarpankaarak Dravya. Rasa Aushadhis like Makshik, Shilajatu, Loha Bhasma, Rasa Sindoor yield promising results in the treatment of Sthaulya. This article focuses on critically reviewing the role of herbomineral drugs mentioned in various Ayur-vedic classics which have remarkable effect in the treatment of obesity.

Surgical Techniques in Ayurveda (Shalakya Tantra-Ent) Mentioned by Acharya Sushruta

In this article, we've covered the ENT surgery methods and techniques that Acharya Sushruta detailed in his famous book, the Sushruta Samhita. The founder of the Sushruta Samhita, Acharya Sushruta, is hailed as the "Father of Surgery" and "Father of Plastic Surgery." An essential component of Ayurveda is Shalakya Tantra, which focuses on the analysis and treatment of conditions affecting the mouth, nose, ears, teeth, throat, head, and eyes. Shalakya Tantra is described as "Shalakayah Yatkarma Shalakyam, Tat Pradhanam Tantram Shalakyam" by Acharya Dalhana. It denotes a location where Shalakas (instruments resembling rods) are utilised for therapeutic purposes. The Shalakya Tantra branch of Ayurveda deals with these instruments and how to employ them for therapeutic purposes. It can be found in numerous Ayurvedic treatises today. Sushruta Samhita contains the majority of the Shalakya Tantra, but it is also found here in fragmented form. Detailed discussions of surgical tools (yantras), various incision kinds, various suturing and bandaging techniques (bandha), fracture reductions, foreign body extraction techniques, etc. are contained in the Sushruta Samhita (about 600 BC). He also brought up the utilisation of reconstructive (Sandhana) surgery by Vaidyas even during the colonial era. Acharya gave a comprehensive explanation of ENT surgery procedures that are largely applicable and actual. Acharya Sushruta noticed that a number of fractures and dislocations connected to ENT can be treated. Today, many of the foreign body removal techniques he described are virtually same to those utilised then. Many conventional surgical techniques are still useful today.These interventions can be a tremendous help in learning new and cutting-edge practises with the help of contemporary advances. Our simple goal in writing this paper is to shed light on all the Shalakya Tantra subjects that are mentioned throughout Sushruta in various places.
