What is Perilla Seed and Perilla Seed Extract?PERILLA SEED EXTRACT-P (powder) 100 - 150mg/day
PERILLA SEED EXTRACT-L (liquid) 150 - 225mg/day
Perilla frutescens and a lot of herbs like lavandula belong to Fam LABIATAE.
Perilla seed has been cultivated in Japan, China, Korea and Southeast Asia and used as spices and also as a major supply for α-linolenate rich oil.
People with allergies are increasing in number every year, and the diet is said to be one of the most important factor for this treatment.
A daily intake of n-6 fatty acids contained in meat or plant oil such as safflower, is accumulated in the body as arachidonic acid which is converted to allergic mediators.
PERILLA SEED EXTRACT inhibits the production of allergic mediators, termed as leukotrienes (LTs).
The mediators are metabolites of arachidonic acid through 5-lipoxygenase (5-LO) pathway.
PERILLA SEED EXTRACT selectively inhibits 5-LO activity (in vitro).
PERILLA SEED EXTRACT also inhibits type IV allergy as well as TPA-induced inflammation (in vivo).
Moreover, the serum IgE levels are suppressed by administration of PERILLA SEED EXTRACT, and in line with this, allergic rhinitis, hay fever and urticaria are significantly improved.
The material used is limited to Perilla leaf from Hokkaido (Japan) from the view point of its quality, its anti-allergic effects and the control of its production. The variety used in the manufacturing process is Perilla frutescens var. acuta Kudo forma viridis Makino.

EXTRACTION OF PERILLA LEAF
The decoction of the dried leaves afforded by boiling water gives an extract with greater anti-allergy activity than that obtained using aqueous ethanol and avoids the precipitation problems caused by chlorophyll etc., in the aqueous ethanol extract (Kosuna et al., 1994).SPRAY DRYING
By the addition of dextrin to the aqueous Perilla extract, followed by spray drying, a stable powdered form is achieved, namely, Perilla extract powder with 1g equivalent to 1ml of Perilla extract. This powder is available for capsule and tablet formulations and for use in a range of health products.MANUFACTURING PROCESS
