Thymus vulgaris ameliorates cough in children with asthma exacerbation: a randomized, triple-blind, placebo-controlled clinical trial.

BACKGROUND: Asthma is one of the most common chronic respiratory diseases with inflammatory involvement and has a high burden worldwide. This study aimed to determine the effect of Thymus vulgaris (TV) on cough in children between 5 and 12 years old with mild to moderate asthma exacerbation. METHODS: In this randomized, triple-blind clinical trial, 60 children between the ages of 5 and 12 with asthma exacerbations were randomly divided into two groups. The intervention group (n = 30) was given TV powder at a dose of 20 mg/kg every 8 hours, prepared as syrup, along with routine medical treatment for a week, and the control group (n = 30) received only routine medical treatment with placebo syrup. At the end of the week, clinical and laboratory symptoms, and spirometry data were re-recorded for both groups. Finally, the recorded factors were compared and statistically analyzed. RESULTS: The results showed that after the intervention, activity-induced cough reduced, and difference was statistically significant between the two groups (p = 0.042), but the reduction in wheezing and breathlessness had no statistically significant difference. Spirometry data showed a significant difference in forced expiratory volume in 1 second (FEV1) between the two groups after intervention (p = 0.048), but this difference was not significant in FEV1/FVC (forced vital capacity), peak expiratory flow (PEF), and forced expiratory flow at 25-75% of the vital capacity (FEF25-75%). CONCLUSION: The results show that TV syrup may be useful as an adjuvant treatment in children with asthma exacerbations.

The efficacy of topical sesame oil in patients with knee osteoarthritis: A randomized double-blinded active-controlled non-inferiority clinical trial.

OBJECTIVE: Sesame oil is an herbal product that has been used to treat the joints pain in several traditional medicines. In this study, we evaluated the efficacy of topical sesame oil versus diclofenac gel in patients with knee osteoarthritis (OA). METHODS: One hundred and four patients were randomly enrolled in two arms of the trial. Patients were treated by topical sesame oil or diclofenac (three times a day) for 4 weeks. Outcome measures were knee pain via visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire, knee joint's flexion angle, 8-meter walk test and number of used analgesics. Patients were evaluated at baseline, 2 and then 4 weeks after the intervention. RESULTS: At the follow-up visits, sesame oil was not inferior to diclofenac regarding scores of WOMAC pain, 8-meter walk test, and knee flexion angle. Although, its non-inferiority was not proved regarding scores of VAS, WOMAC stiffness, and WOMAC total at the 4th week. Moreover, sesame oil was not inferior to diclofenac regarding consumed analgesics. CONCLUSION: It seems that the topical sesame oil was non-inferior to diclofenac gel on the reduction of the knee OA pain and improvement of some indicators of its function.

Pruritus Treatment in Viewpoints of Traditional Persian Medicine.

BACKGROUND: Pruritus is an unpleasant feeling that can cause the desire of scratching in a person and can be the symptoms of systemic, infectious, and neurological diseases. Pruritus is the most common clinical manifestation of skin diseases. Pruritus prevalence is 8-38% in the general population. Causes and treatments of pruritus have been described by traditional Persian medicine scientists. The aim of this study was to derive general principles of the proposed treatment to reduce or relieve pruritus. METHODS: This descriptive study, review traditional medicine books including Al canon fil tibb, Al-Hawi, Makhzan ul-adviyyah, Al-Abniyah an-Haghyegh el-adviyah, Tuhfat ul-Momineen and Exir-e-Azam. The above-mentioned documents were derived and classified by keywords such as pruritus, hakka, jarab and sherry. RESULTS: In traditional Persian medicine, there are different causes for pruritus such as accumulation of vapors or acute humors in subcutaneous tissue or weakness of expulsive (Dafi'a) faculty and its treatment is based on removing the causes. Proper nutrition, bathing, and removing pathogenic humors are involved in the treatment. According to this study, some plants such as Cassia fistula, Purslane, Violets, Fumaria, Barley, Coriander, Rose and Terminalia chebula are anti-itching. CONCLUSION: Proper nutrition is the most important point in health and treatment of humors production with appropriate quality and quantity. Pruritus can be treated by lifestyle modification and using medicinal plants. It could be concluded that traditional Persian medicine therapies can be effective in the treatment of pruritus with mild side effects. By further investigation and research, we can reach more effective treatment methods in the field of traditional Persian medicine along with other new medical therapies.

The Role of Nutrition in the Prevention and Treatment of Cancer in Traditional Persian Medicine.

BACKGROUND: Cancer is the most important non-communicable disease and the chief cause of death in the world, which imposes a major burden on communities. It is expected that the number of new cancer cases will increase 70 percent worldwide in the next two decades. The exact cause of the disease is unclear in modern medicine. More than a third of all cancer cases are preventable and the other two third are treatable if detected early. Cancer is a type of swelling in traditional Persian medicine (TPM). The aim of this study was to investigate the role of nutrition in the prevention and treatment of cancer in TPM. METHODS: This study is a review-descriptive that was conducted based on traditional medicine books, including Al Canon fil tibb, Al-Hawi, Zakhireh-ye Khwarazm shahi and Exir-e-Aazam. RESULTS: From the viewpoint of TPM, swelling is any abnormal accumulation of material in organs that will make bulging and dysfunction. If the substance of the disease can be fully matured and eliminated in the early stages of swelling and the patients become stronger, the possibility of swelling creation with poor prognosis such as cancer will decrease. Cancer is a cold and melancholic (soda) swelling that can be created by burning of humors. Treatment of cancer is based on specific nutrition management and medicinal herbs. According to the study, eating moderate to moisture temperament foods that can decrease acuity of melancholy humor (soda), produce appropriate blood (e.g. lamb, goat, egg yolks) and avoiding foods producing melancholy humor are recommended. CONCLUSION: Swelling is a compound disease and cancer is a melancholic swelling. According to TPM, treating swelling in the early stages is possible and by observing the principles of nutrition, eating and drinking rules, and proper and early treatment of hot swelling and turning hot swelling into cold, cancer can be prevented.
