What it is
Tinospora cordifolia, known as Guduchi (गुडूची) or Giloy (गिलोय), is a climbing shrub native to India. Its stem extract has been evaluated in a randomised double-blind placebo-controlled trial for allergic rhinitis, showing 100% relief from sneezing in 83% of patients, significant reduction in eosinophil and neutrophil counts, and absence of goblet cells in nasal smear. It is one of the most important Rasayanas (rejuvenative tonics) in Ayurveda.
