Hydroalcoholic Extract (1:5 | 40% alcohol) Mixture of Shiso (Perilla Frutescens) and Immortelle (Helichrysum Itallicum) tinctures. Perilla Frutecens or Shiso is a plant used for millennia in Traditional Chinese Medicine as an anti-allergy, anti-asthmatic, antitussive, expectorant and antibiotic. Immortelle acts by stimulating the internal secretion of hydrocortisone and has anti-allergic, anti-inflammatory and expectorant properties. The plants used in this tincture are grown in our garden.
