New package design for "Tsurunel Jelly," effective for sudden leg cramps, to be released

Sato Pharmaceutical Co., Ltd. (Head Office: Kashihara City, Nara Prefecture; President and CEO: Masahiro Sato) will renew and release the package design for "Tsurunel Jelly" (Class 2 OTC Drug), a jelly-type Kampo medicine effective for sudden leg cramps, on Tuesday, July 7, 2026. In addition to the existing 4-stick pack, a new 14-stick pack, offering a more affordable price per stick, has been added to the lineup.

"Tsurunel Jelly" (Class 2 OTC Drug) New Package Design

Product Name: Tsurunel Jelly (Class 2 OTC Drug)

Retail Price: 4 sticks / \1,408 (\1,280 excluding tax), 14 sticks / \3,784 (\3,440 excluding tax)

"Tsurunel Jelly" is a jelly-type Kampo medicine formulated with Shakuyaku Kanzo To extract, which is effective for sudden leg cramps and muscle spasms. It has a muscat flavor that masks the unique taste of Kampo medicine and can be taken anywhere without water. Its stick type makes it convenient to carry for sudden symptoms during exercise or when out and about.

To meet the demand in sports scenes, the package design has been renewed. The sharp, diagonal lines are inspired by the scene of use, approaching sudden symptoms during exercise with rapid effect*. The main color is blue, evoking the soothing of pain from calf cramps and muscle spasms.

*Rapid effect means addressing concerns early.

To commemorate this renewal, Ilhope Inc. conducted doping analysis on "Tsurunel Jelly." Anti Doping Action is an anti-doping program provided by Ilhope Inc. Based on the WADA Prohibited List (Prohibited List International Standard) and JADA's published guidelines (https://www.playtruejapan.org/entry_img/s-guideline.pdf), they analyze doping prohibited substances that have a high risk of contamination in products such as supplements. The Anti Doping Action logo is a mark of quality assurance that can only be used on products that meet these strict standards.

Our company is based in Nara Prefecture, which has a deep connection with medicinal herb cultivation due to its long historical and cultural background. We are engaged in initiatives that incorporate the concept of "6th industry" (integrated production, processing, and sales), from cultivation of medicinal herbs to product manufacturing and sales. As part of this effort, for this product, we use self-cultivated Nara-grown peonies for a portion of the Shakuyaku Kanzo To extract formulated as an active ingredient.
