  1. This site is amazing as I got all the information about yava kashra leaving its scientific name I would like you to add its scientific name also

  2. Good effort…kindly clear my doubtd
    Here filtering was advised as 3-4times..describe in detail.
    1)after 1st filtration, whether the obtained liquid was refiltered for 2 more times or have you again added 4times water to the sediment left for night & then filtered…
    2)if ash was washing every time…why only 4times times it was washed ..any specification…

    • Hi,
      1. After 1st filtration, the obtained liquied is re-filtered for 2 more times. Do not add water to it further.
      2. That is the traditional method which is prescribed to make this product. Usually in making kashaya, ghrita etc also 4 times principle is applied. The ancient seers might have used trial and error method to come to this conclusion.
