About this app

Learn about the classics of Oriental medicine related to seasons and time.

"Takada's Herbal Medicine Clock" is a clock app designed to help you feel the passage of time and seasons, and to harmonize your mind and body.

Since ancient times, Oriental medicine has believed that various physical and mental symptoms arise in response to the natural cycles (seasons and time). This app beautifully visualizes the current "24 solar terms" and the "irregular time system of the twelve zodiac signs" derived from the sunrise and sunset cycles, and delivers you classical texts related to optimal health care and treatment for each moment.

■ Main Features and Functions of "Takada's Herbal Medicine Clock"
━━━━━━━━━━━━━━━━━━━━━
◆ 1. A Beautiful and Evocative "Twelve Zodiac Signs and Irregular Time System" Clock
Based on sunrise and sunset times, it beautifully expresses the passage of time throughout the day using the twelve zodiac signs (Rat, Ox, Tiger, etc.). You can visually experience the "living time" that ancient Japanese people felt, closely aligned with the changes in the length of day and night.

◆ 2. Linked to the Twenty-Four Solar Terms
Displays indicators of the Eastern seasons, which divide the year into 24 equal parts, such as the beginning of spring, the spring equinox, the summer solstice, the heat of summer, the autumn equinox, and the winter solstice. You can feel the deepening of the seasons along with the visual gradation of colors, indicating which season and stage you are currently in.

◆ 3. Classical Texts of Oriental Medicine Related to Time, Seasons, and Weather
Classical texts backed by history are extracted in real time in accordance with the changing time, seasons, and weather.
* 'Huangdi Neijing Suwen' (Yellow Emperor's Classic of Internal Medicine): The oldest bible of Oriental medicine
* ​​'Shanghan Lun' (Treatise on Febrile Diseases): A classic of clinical medicine
* ​​'Yang Sheng Jun' (Principles of Health Preservation): The secrets of health expounded by Kaibara Ekiken, a scholar of the Edo period
Both the original Chinese text ("plain text") and a modern Japanese translation ("written in Japanese") that conveys its profound meaning are displayed side by side.

◆ 4. Japanese Modern Design Themed on Serenity and Harmony
An elegant and premium design inspired by the Yin-Yang Five Elements theory and traditional Japanese colors. The clock face, which changes moment by moment, offers a meditative experience that soothes the mind just by looking at it.
