BACKGROUND: Although Ayurveda medicine is used to manage bronchial asthma, available evidence relating to its efficacy needs to be generated. To scientifically evaluate the efficacy and safety of Ayurveda interventions, Kantakaryavaleha and Eladi Gutika, a multicenter, prospective, single-arm, open-label clinical study on mild stable bronchial asthma (Tamaka Shwasa) will be initiated. MATERIALS AND METHODS: 90 patients (45 in each center) with mild stable bronchial asthma will be enrolled based on inclusion and exclusion criteria. All the patients will be treated with Ayurveda medicines, i.e., Kantakaryavaleha 10 g, orally, twice daily with lukewarm water and tablet Eladi Gutika, 1 g thrice daily, orally. The intervention period will be 12 weeks and each participant will be followed up for 2 more weeks post intervention period. The primary outcomes will be measured assessing the change in the Asthma Control Questionnaire and the frequency of need for control medication before and after the trial intervention. The secondary outcomes will be measured by comparing the changes in clinical signs and symptoms of Tamaka Shwasa as per the Ayurveda classical text, changes in forced expiratory volume (FEV1), and biomarkers such as serum C-reactive protein (CRP), and IgE. TRIAL REGISTRATION: The trial has been registered at the Clinical Trials Registry-India (CTRI); the registration number for this trial is CTRI/2018/06/014425.

| Introduction|| |
Background and rationale
Tamaka Shwasa (bronchial asthma) is one of the pathological conditions mentioned under five types of Shwasa Roga (respiratory disorders) in Ayurveda., It is an independent disease with its own etiology, pathophysiology, and management. According to the classics of Ayurveda, Tamaka Shwasa is a Yapya Vyadhi (a disease of the chronic nature and difficult to cure). Though it is a disorder of Pranavaha Srotas (respiratory system), other Srotas (channels) might also be involved. The analogous disease entity in contemporary medical science to Tamaka Shwasa is bronchial asthma. Bronchial asthma is a chronic inflammatory disease of the airways characterized by bronchial hyperreactivity and a variable degree of airway obstruction. Genetic predisposition toward the production of IgE antibodies in response to pollen, house dust mites, fungi, or animal-derived proteins, etc., are the most important risk factors for bronchial asthma. This disease is commonly diagnosed based on the clinical history, physical examination, and pulmonary function tests, including reversibility testing and the measurement of bronchial reactivity. According to recent data, bronchial asthma afflicts about 10% of children and 5% of adult and about 300 million people worldwide. The World Health Organization (WHO) estimates the number of disability-adjusted life years (DALYs) lost to asthma at 15 million per year, corresponding to 1% of the global loss of DALYs due to illness., The Global Initiative for Asthma (GINA) in the 2006 update proposed a new classification of asthma, based on the level of control rather than the previous classification based on the severity of the underlying disease process. Long-term treatment with inhaled corticosteroids is the basis of asthma treatment, alongside preventive measures and patient education. Several medicines are available, but they have many serious side effects. None of the available treatments are effective in providing a complete cure for this disease. Thus it was proposed that the asthma treatment goal, regardless of a patient’s asthma severity, should lead to the achievement of complete disease control. In addition, the prevention of future risks should also be intended., The goal of management is to control the symptoms of the disease effectively and in a lasting fashion. Therefore, there is a need to search for a new therapeutic agent with no or minimal side effects., Ayurveda in its texts has lots of herbomineral compounds, which can fill up this gap. The classics of Ayurveda contribute several modalities of treatment for Tamaka Shwasa. Among all treatment modalities, herbal combinations are well-accepted, mostly easily available, and also effective in asthma control. Thus, based on textual and clinical experience, classical Ayurveda formulations, Kantakaryavaleha and Eladi Gutika are selected for clinical trial to study their role in disease control among patients with bronchial asthma.
To evaluate the safety and efficacy of classical Ayurveda formulations Kantakaryavaleha and Eladi Gutika in the management of mild stable bronchial asthma (Tamaka Shwasa).
This will be a multicenter, prospective, single-arm, open-label, clinical study.
| Materials and Methods|| |
The study will be conducted at Central Ayurveda Research Institute (CARI), Patiala, Punjab, and Regional Ayurveda Research Institute (RARI), Vijayawada.
Following are the inclusion criteria: Patients of either sex with age between 18 and 60 years, diagnosed with mild predominant or persistent stable bronchial asthma (Tamaka Shwasa) (as per GINA guidelines); forced expiratory volume (FEV1) >80% of the predicted value; and patients’ willingness to participate and sign written consent.
Following are the exclusion criteria: patients with diabetes mellitus, chronic obstructive pulmonary disorder, malignancy, etc.; patients with unstable cardiovascular disease; patients suffering from other major systemic illness that may influence the study; patients with liver function tests, aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >2 times upper normal limit, or serum creatinine more than the upper limit of normal value; pregnant or lactating women will be excluded from the study.
All the participants will be treated with traditional Ayurveda medicine, i.e., Kantakaryavaleha, 10 g, orally, twice daily with lukewarm water and tablet Eladi Gutika, 1 g thrice daily, orally [Table 1]. Quality assured trial interventions would be procured from GMP certified pharmacies. To alleviate emergency (if any occurred), the use of rescue medication will be done. The same need to be documented in an appropriate column in the case report form (CRF).
Primary outcome measures
Change in score of Asthma Control Questionnaire (ACQ) and dependency on standard of care in the form of Asthma control medication.
Secondary outcome measures
Change in FEV1, Serum C Reactive Protein and IgE; frequency of rescue medication and incidence of adverse events.
A total of 90 participants will be enrolled at the two study centers. All the participants will undergo a 12-week treatment and a 2-week follow-up period. A washout period of 2 weeks will be provided to the participants who are already taking any traditional medicine other than standard of care. Time-line of the study events is mentioned in [Table 2].
The sample size was calculated based on the primary outcomes, which was the change in Asthma Control Questionnaire (ACQ) from baseline to week 12. Based on the previous studies, anticipating a change of 1.05 in ACQ, and assuming a standard deviation of 2.25 points with 95% confidence level (α = 0.05 and 80% power, the sample size is 36. Anticipating a drop out of 20%, the sample size was estimated as 43 (36.04 + 7.20 = 43.24) and rounded off as 45 at each centre.
Enrollment of participants
The patients in OPDs of the study centers and medical camps organized by the study centers will be sensitized about this study. The willing patients will be screened for eligibility. After obtaining the informed written consent from the eligible participants, they will be enrolled in the study who will undergo the baseline assessments.

| Discussion|| |
Tamaka Shwasa is a chronic inflammatory condition of the lung airways resulting in episodic airflow obstruction. This disease is more predominant in children and the aged population. The parallel disease entity in contemporary medical science to this disorder is bronchial asthma. Bronchial asthma is a significant health issue, especially in developing countries like India and is responsible for significant morbidity. It is a chronic inflammatory disorder of the airways characterized by bronchial hyperresponsiveness and variable airflow obstruction that is often reversible either spontaneously or with treatment. According to Acharya Sushruta, when the natural association of Prana Vayu (one of the five subtypes of Vata that is seated in head) is hindered and it is coupled with Kapha, afterward it leads to the origin of Shwasa Roga (respiratory disorders). The genesis of respiratory disorders first involves only vitiation of Vata dosha all over the body. This vitiated Vata, which is in Urahasthana (chest/thorax), in turn creates Rukshata (~roughness), Sankocha (~constriction), and Kharata (~roughness) in Pranavaha Srotas (respiratory system). Vitiated Vata affects the normal Kapha in Urahasthana (chest/thorax), which results in Vilomata (moves in the wrong direction) of Prana Vayu through the obstruction to its natural movement by Kapha. In the other way, both Vata and Kapha get vitiated independently along with the production of Amavisha (symptoms of Amavisha), which eventually contributes to the manifestation of respiratory disorders. In the present study, Kantakaryavaleha and Eladi Gutika have been selected for the management of mild stable bronchial asthma. However, a large number of medicines in the form of Avaleha (semi-solid preparation) have been described for the treatment of respiratory disorders as these have Brimhana (nourishment) property, which is important to prevent the pathogenesis of this disease.,, The selected formulation Kantakaryavaleha possesses several potential herbal ingredients that are efficient to combat the pathophysiology of mild stable bronchial asthma (Tamaka Shwasa). Along with Tamaka Shwasa, the formulation also acts in pacifying symptoms of other respiratory diseases such as Hikka (hiccough), Kasa (cough), and Shula (pain). The other drug Eladi Gutika is also beneficial in management of Chardi (vomiting), Hikka (hiccough), Kasa (cough/tussis), Bhrama (vertigo), Murccha (fainting), Raktapitta (bleeding disorders), Rakta Nishthivana (hematemesis), Jvara (fever), Trishna (excessive thirst), Aruchi (anorexia), Parshwa Shula (flank pain), Shosha (emaciation), Pliharoga (spleen disorders), Amavata (rheumatism due to Ama/rheumatoid arthritis), Svarabheda (hoarseness of voice), and Shukra Kshaya (diminution of semen). The protocol was designed for assessment of clinical outcome of Kantakaryavaleha and Eladi Gutika in the treatment of Tamaka Shwasa (mild stable bronchial asthma). If found effective, the selected drug, i.e., Kantakaryavaleha and Eladi Gutika can be studied for evaluation of their efficacy through randomized controlled trials on larger sample size.
