Holy Basil (Tulsi) CO2 has a wonderfully sweet, leafy, earthy, tobacco-like aroma. Interestingly, Holy Basil is a cherished Hindu ceremonial herb and is also often found in Thai cooking. It's also said to aid in stress reduction and protect against a wide range of pathogens. It's worth nothing that this material is quite viscous, almost cream-like, therefore may require some care before blending. Holy Basil blend well with citrus oils, Jasmine, Ylang Ylang, and Sandalwood.
