Objectives

Narrative objectives1

Umesu phenolics (UPs), industrially derived from a by-product of the mume fruit (Japanese apricot), are composed of hydroxycinnamic acid derivatives. UPs inhibit the multiplication of common cold and influenza viruses and have virucidal effects. We conducted a clinical trial to examine the effects of gargling with UPs on the incidence of common cold and influenza in healthy subjects.

Assessment

Primary outcomes

The incidence and duration of common cold/influenza over the full 9-week trial period. The incidence and duration of common cold and influenza symptomatic days by week.

Key secondary outcomes

The incidence and duration of common cold and influenza symptoms(runny nose, sneezing, sore throat/throat discomfort (irritation), headache, cough, expectoration, fever, joint pain, and fatigue/malaise) over the full 9-week trial period. The incidence and duration of common cold and influenza symptoms by week.

Interventions/Control_1

Two groups: a group that gargled with granules containing UPs (UP group) and a group that gargled with granules not containing UPs (placebo group).

Interventions/Control_2

The 2 g/packet UP granules used in the present study contained 125 mg UPs and were dissolved in 100 mL water to achieve a gargle with a UP concentration of 1.25 mg/mL. The 2 g/packet placebo granules did not contain UPs. Participants gargled with the granules dissolved water three times a day for 9 weeks.

Results

After 9 weeks of gargling, common cold/influenza incidence in the UP group and placebo group were 13.3% and 13.6%, respectively, showing no significant difference. Gargling with UPs was estimated to significantly shorten the number of symptomatic days per incidence by approximately 3 days at 9 th week. The number of days on which sneezing occurred was significantly (p < 0.05) lower in the UP group.

Baseline Characteristics

The baseline characteristics of the participants are summarized as below. The two groups did not demonstrate any differences in sex, age, current illnesses, medical history (hypertension, diabetes, etc.), regular gargling (yes or no), or type of gargle used. Influenza vaccination was significantly less common in the placebo group.

Participant flow

The 300 participants, 149 were in the placebo group, while 151 were in the UP group. Five participants in the placebo group discontinued the trial due to circumstances unrelated to the trial itself (change of residence, change of job, etc.).

Adverse events

No notable adverse events were observed in either group during or after the trial period.

Outcome measures

Outcomes consisted of the following: incidence and duration of common cold/influenza, and incidence and duration of common cold/influenza symptoms, i.e., runny nose, sneezing, sore throat/throat discomfort (irritation), headache, cough, expectoration, fever, joint pain, and fatigue/malaise. For incidence of common cold/influenza and their symptoms, the mean weekly incidence rate was used as an assessment indicator. For duration of common cold/influenza and their symptoms (symptomatic days), the mean number of days per week was used as an assessment indicator. These assessment indicators were compared between the placebo group and UP group for the overall 9-week period and on a weekly basis.
