Efficacy and Safety of Saururus chinensis Extract (LHF618) for Treating Allergic Rhinitis: A Randomized,...

Area of Science:

• Immunology
• Pharmacology
• Allergology

Background:

• Allergic rhinitis (AR) is a prevalent global health issue impacting quality of life.
• Existing treatments offer temporary relief and potential adverse effects, necessitating alternative therapies.
• Investigating natural compounds for AR management is crucial.

Purpose of the Study:

• To evaluate the efficacy and safety of standardized Saururus chinensis extract (LHF618) for allergic rhinitis symptom relief.
• To assess LHF618's impact on rhinitis control and specific immunoglobulin E (IgE) levels.
• To determine the tolerability and safety profile of LHF618 in AR patients.

Main Methods:

• A 4-week clinical study comparing LHF618 to a placebo.
• Assessment of total nasal symptom scores, including itching, sneezing, and congestion.
• Measurement of rhinitis control assessment test scores and dust mite-specific IgE levels.

Main Results:

• LHF618 significantly reduced total nasal symptom scores compared to the control group.
• Patients receiving LHF618 showed improved rhinitis control assessment scores.
• A significant reduction in dust mite-specific IgE levels was observed with LHF618 treatment.
• No significant adverse effects were reported, indicating good tolerability.

Conclusions:

• Standardized Saururus chinensis extract (LHF618) is an effective and safe option for alleviating allergic rhinitis symptoms.
• LHF618 shows promise as a natural alternative therapy for allergic rhinitis, especially for dust mite allergies.
• Further research into LHF618 could support its integration into AR management strategies.
