Evaluation of the Antihistamine and Anti-Inflammatory Effects of a Nutraceutical Blend Based on Quercetin, Perilla frutescens, Boswellia serrata, Blackcurrant, Parthenium, Helichrysum, Lactobacillus acidophilus and Bifidobacterium animalis Through In Vitro and In Vivo Approaches—Preliminary Data

TL;DR

A nutraceutical blend was tested for its antihistamine and anti-inflammatory effects in lab and animal studies, showing potential as a new allergy treatment.

Contribution

The study introduces a novel nutraceutical blend and provides preliminary evidence of its antihistamine and anti-inflammatory effects.

Findings

The blend reduced histamine degranulation in RBL-2H3 cells by about 30%.

The mixture interfered with histamine wheal development in vivo by up to 30%.

The blend reduced TNF alpha levels by about 13% in vitro.

Abstract

Respiratory and food allergy conditions are increasing internationally and the most commonly used drugs in these conditions are antihistamines, products that can interfere as histamine receptor antagonists. In accordance with the need to test new principals capable of developing fewer side effects, we preliminarily studied the therapeutic antihistamine effect in vitro and in vivo of an innovative nutraceutical blend based on Quercetin, Perilla frutescens, Boswellia serrata, Blackcurrant, Parthenium, Helichrysum, Lactobacillus acidophilus and Bifidobacterium animalis. The in vitro test demonstrated the interaction between the examined mixture and a rat leukemia cell line (RBL-2H3) widely used as a model simulating mast cells in immunological and allergological studies; this pre-clinical test demonstrated a statistically significant reduction in cell histamine degranulation (about 30%). The in vivo test demonstrated instead that the mixture interferes up to 30% in the development of histamine wheal. In addition, during the in vitro test, we also tested the effect of the mixture on allergic inflammation, so we evaluated the interference of the mixture on TNF alpha levels, determining a reduction in tested concentrations of about 13%.
