Support healthy respiratory system function with Khella liquid extract from Herb Pharm. We prepare our Khella Extract from the seeds of Ammi visnaga plants which are Certified Organically Grown &/or Sustainably Wildcrafted in their natural habitat. To assure optimal extraction of Khella's bioactive compounds, the seed is hand-harvested only when fully mature, is cleaned of superfluous plant materials, and is then thoroughly extracted. Seek expert medical advice before taking during pregnancy. Avoid prolonged exposure to sunlight after ingestion.
