This product is a jelly type that can be taken without water, allowing for immediate administration when needed, such as during sleep, exercise, or travel. With its refreshing Muscat flavor, it is an easy-to-take dosage form for those who dislike powders or tablets.

◆ Background of Development

Leg cramps and muscle spasms are symptoms that can occur suddenly in various daily situations, such as during sleep, exercise, or travel, and require immediate attention.

Since ease of administration can be an issue when away from home, we developed a jelly-type pharmaceutical that can be taken anywhere without water, anticipating such usage scenarios.

Furthermore, to accommodate those who have the impression that Kampo medicines are "bitter" or "difficult to drink," we aimed to reduce the burden of administration by making it a Muscat-flavored jelly.

◆ Product Features

Can be taken without water

Since it can be taken as is, it is an easy-to-handle dosage form for situations where sudden leg cramps are a concern, such as during sleep, exercise, or travel.

Individually packaged in a convenient size for portability

Individually packaged for single use, it is easy to carry and can be taken immediately when needed, even when away from home.

Easy to take for those who dislike powders or tablets

By making it a jelly, we have considered ease of administration.

Muscat flavor that is easy to take even for those who dislike the taste of Kampo medicine

The refreshing Muscat flavor masks the unique bitterness of Kampo medicine.
