| *Jaiswal et al, 2011, in a clinical survey<ref> Jaiswal Rahul et al, 2011 </ref> found a significant relation between seasonal variation and prevalence of some diseases viz.

They also observed that there is seasonal variation in the state of [[agni]] and [[bala]] (strength) of the person, as stated by our ancient seers. | | *Jaiswal et al, 2011, in a clinical survey<ref> Jaiswal Rahul et al, 2011 </ref> found a significant relation between seasonal variation and prevalence of some diseases viz.

| *Nathani et al, 2013, in a clinical research<ref> Nathani Neeru et al, 2013 </ref> found that maximum number of patients of [[tamaka shvasa]] (bronchial asthma) were registered in winter seasons ([[hemanta]] and [[shishira]]), [[vasanta]] and [[varsha]]. These seasons were the predominant period of asthma attack in majority of cases. In maximum number of cases the attack of [[tamaka shvasa]] gets precipitated by intake of [[kapha]] and [[vata]] vitiating [[sheeta]], [[guru]], [[madhura]] and [[amla]] [[rasa]] predominant [[ahara]] like ice-cream, cold drink, cold water, fruit juices, curd, sweets, rice, pickle, salad with lemon etc. in all seasons. | | *Nathani et al, 2013, in a clinical research<ref> Nathani Neeru et al, 2013 </ref> found that maximum number of patients of [[tamaka shvasa]] (bronchial asthma) were registered in winter seasons ([[hemanta]] and [[shishira]]), [[vasanta]] and [[varsha]].

| + | A research was conducted with the objective of revalidating the principle of checking the purity of hansodaka. Physico-chemical and microbiological analysis of water during the rise of the Canopus star in the autumn season in different water reservoirs was carried out. In 2015, two litres of water was collected in sterilized glass bottles from water reservoirs, Rakkaskoppa and Fort Lake. In 2016, water samples were collected from Jamboti water. Physico-chemical and microbiological analyses were done at three different periods, like before 15 days of rise of Canopus star, during rise of Canopus star and after 15 days of rise of Canopus star.The physico chemical analysis of water during Canopus star showed that the values of pH, total alkalinity, CaCO3, sulphates, chlorides, biological oxygen demand level were decreased. A reduction in microbiological bacterial count was observed but no changes were noted with fungal count. From these results, it can be interpreted that there was a positive effect of Canopus star on the purification of water, physico chemical and microbiological parameters.However,the results may vary on the level of contamination and environmental conditions.<ref>Savita Sajjan,Vedantam Giridhar.A Novel Study on Physico Chemical and Microbiological Analysis of Water |
