Brief summary: The goal of this clinical trial is to test AllerPops' effectiveness in people who suffer from allergic rhinitis. The main question\[s\]it aims to answer are:

1. To assess the effectiveness of AllerPops on relieving nasal symptoms compared to the control group in volunteers with seasonal/year-long allergies during the first 7 days of the 21-day intervention period.
2. To evaluate the safety of AllerPops administration in volunteers with seasonal/year-long allergies during a 21-day intervention period.

Up to 30 days between Screening (V1) and Baseline (V2), and a 21-day intervention period, with dosing occurring every other day for a minimum of 3 doses, and thereafter until the participant is satisfied with the relief of the nasal allergy symptoms. The suitable season for the trial will be determined based on the seasonal variation measures.

Researchers will compare slow and fast consuming groups to see if the way of use impact the effectiveness.

Detailed description: Duration: Up to 30 days between Screening (V1) and Baseline (V2), and a 21-day intervention period, with dosing occurring every other day for a minimum of 3 doses, and thereafter until the participant is satisfied with the relief of the nasal allergy symptoms. The suitable season for the trial will be determined based on the seasonal variation measures.

Primary Objectives: To assess the effectiveness of AllerPops on relieving nasal symptoms compared to the control group in volunteers with seasonal/year-long allergies during the first 7 days of the 21-day intervention period.

Secondary Objective:

1. To evaluate the safety of AllerPops administration in volunteers with seasonal/year-long allergies during a 21-day intervention period.
2. To assess the duration of effectiveness of AllerPops in relieving nasal symptoms compared to the control group in volunteers with seasonal/year-long allergies during a 21-day intervention period (exploratory).
3. To evaluate the effect of the AllerPops administration on the oral microbial presentation/microbiota using Amplicon Metagenomics Sequencing test through saliva samples during a 21-day intervention period (exploratory).
4. To evaluate the effect of the AllerPops administration on the IgE (total) blood level during a 21-day intervention period (exploratory).

Study Population: Seventy-two participants with seasonal/year-long nasal allergies.

Eligibility criteria: Inclusion Criteria:

* 1. Participants will be clinically diagnosed with persistent or intermittent allergic rhinitis, according to the Allergic Rhinitis and Its Impact on Asthma (ARIA) classification. (The guidelines of Allergic Rhinitis and its Impact on Asthma (ARIA) group, classified it to intermittent (less than 4 days per week and for less than 4 weeks) and persistent (more than 4 days per week or lasting more than 4 weeks regardless of the number of days per week).

  2. Male or female seasonal/year-long nasal allergy sufferers (as assessed by a questionnaire at screening) between the ages of 18 and 70.

  3. Females who are not of childbearing potential (post-menopausal defined as those with amenorrhea for at least 2 years). Females of childbearing potential should be either sexually inactive (abstinent) for 60 days prior to the first dose of the study, throughout the study and for 30 days after completion of the study, or be using one of the following acceptable methods of birth control: i. Surgically sterile (bilateral tubal-ligation, hysterectomy, bilateral oophorectomy) for at least 90 days prior to the first dose of the study.

ii. IUD in place for at least 60 days prior to the first dose of the study, throughout the study and for 30 days after completion of the study.

iii. Barrier methods (condom, diaphragm) with spermicide for at least 60 days prior to the first dose of the study, throughout the study and for 30 days after study completion.

iv. Hormonal contraceptives for at least 90 days prior to the first dose of the study, throughout the study, and for 30 days after study completion.

* Changes to the method of birth control while participating in the study will be judged by the PI for acceptability.
