    • Management for allergies may involve avoidance of the allergen, medications to relieve

      66

      symptoms, or allergen immunotherapy (AIT) to desensitize the immune system to the allergen.

      While allergen specific immunotherapy is the only known disease modifying therapy for type I allergies,

      89

      there is no such treatment available for type IV allergies.

      Several guidelines applicable for allergen products are available (see section 3) and provide advice on

      94

      quality and clinical development according to the current knowledge.

      However, this guideline does not cover the indication of atopic dermatitis or asthma as these

      128

      conditions will require separate clinical trials (see Section 6).

      In addition, the guideline does not cover medicinal allergen products manufactured using recombinant

      130

      DNA technology, synthetic peptides, DNA or RNA constructs and/or cell preparations as they differ

      131

      substantially to the allergen products as discussed above.

Whiskey Meets the Nectar of the Gods! A Texas Whiskey Festival and Ranger Creek Collaboration.

CEDAR PARK, Texas, Sept. 22, 2022 /PRNewswire-PRWeb/ -- Ancient Greeks dubbed mead the "nectar of the Gods." It is a fermented combination of honey, water, fruits, and spices. Rarely aged in oak barrels makes finding a used barrel difficult. After a year of searching, Austin, TX-based Meridian Hive had one. A gem of a barrel, French oak that aged, fermented orange blossom honey and red wine grapes. Perfect for Ranger Creek's bourbon and our second Tejas Collaboration. Bourbon finished in a mead barrel!
