Smudging has been used since ancient times for healing and to clear the accumulated emotional or spiritual negativity. White sage (Salvia apiana) has been used for centuries by the Native Americans for their ceremonies and healing sessions. Burning the dry leaves of this sacred herb is believed to cleanse any negative stuck energies and a space of any evil spirits. The Aura (the electromagnetic field)   around our body, as well as the energy in our environment, can get blocked with harmful positive ions that can cause feeling of fatigued, sluggish and burnt out. Sage smudge neutralizes positive ions by its negative ions and thus help in changing the energy  from negative to positive.Recent studies have shown that there is scientific evidence that medicinal smoke is a powerful antiseptic that can purify the air of 94% of harmful bacteria for up to 24hours.Carefully burning sage may be a blessing for those  with allergies, asthma, bronchitis  and other respiratory conditions.It contains thujone which is mildly psychoactive. It’s actually found in many plants used in cultural spiritual rituals to enhance intuition.
