The name Three Treasures of Chinese Medicine in Chinese...

精, 氣, 神 are the characters jing, qi, and shen.

As a set, these three characters are known in English as the treasures of traditional Chinese medicine, the treasures of Qi Gong, or the three treasures of Taoism / Daoism.

Sometimes this set is titled 三寶 (sānbǎo) or “three treasures,” but here, we're writing each treasure out.

Here's how these characters are perceived in this context...
Jing: nutritive essence; refined; perfected; pure
Qi: vitality; energy; force; breath; vigor
Shen: spirit; soul; mind; being

To keep it simple, you can use “essence, vitality, and spirit” to define these.

三寶 is the title for “Three Precious Treasures of Buddhism” or “The Triple Gem.”

These three treasures are the Buddha 佛, the Dharma 法 (teachings or the law of the Buddha), and the Sangha 僧 (the community of monks or followers).

This term is used by most (perhaps not all) Buddhists in China, Japan, and South Korea (written the same in the original form but pronounced differently in each language). Non-Buddhists may just read this as “Three Treasures” without the religious context. For instance, there is also a “Three Treasures of Chinese Medicine” that is sometimes titled the same way.

In modern Japanese and Simplified Chinese, this is written 三宝 instead of 三寶.
