6. Aids fasting
   Mentioned in the Shen Nong Ben Cao Jing as part of the superior class of animal parts which can, with protracted taking, make the body light, enable one to communicate with the Spirit Light (Shen Ming 神明), and lengthen the lifespan. This may suggest it was part of supplementing the diet when engaging in an "avoiding grain" (Bigu 辟穀) fasting regime to cultivate life (Yangsheng 養生).

Standard Dosage: 15-30g in decoction.
Cautions: The high mineral content of this medication may prevent the oral absorption of the fluoroquinolone class of antibiotics.

Animal products are prohibited from use in the UK under the Medicines Act 1968 ch. 67 which restricts herbalists to the use of plant products only. It is generally substituted with Bai Shao and Wu Wei Zi.

If viewed from a western perspective as a source of calcium which may cause sleep disturbances, then supplementation or inclusion of high calcium/magnesium content herbs (e.g. Kun Bu) could be considered, especially if other signs such as oesteoporosis or muscle cramps are present and risk of side effects from calcium/magnesium supplements are low (stones, calcified arteries, GI issues). However, this assumes a mechanism which does not match many of the traditional patterns for which it is prescribed.

This may suggest it was part of supplementing the diet when engaging in an "avoiding grain" (Bigu 辟穀) fasting regime to cultivate life (Yangsheng 養生).

Standard Dosage: 15-30g in decoction.
Cautions: The high mineral content of this medication may prevent the oral absorption of the fluoroquinolone class of antibiotics.

Caution should also be taken due to the possibility of heavy metal absorption from the oysters' environment. If decocting it is advisable to leave the dregs at the bottom as heavy metal particles will naturally sink. It is still probably advisable to avoid for long term use unless the source is known to be clean.

Animal products are prohibited from use in the UK under the Medicines Act 1968 ch. 67 which restricts herbalists to the use of plant products only. It is generally substituted with Xuan Shen, Bai Shao and Wu Wei Zi or Tian Ma.

If viewed from a western perspective as a source of calcium which may cause sleep disturbances, then supplementation or inclusion of high calcium/magnesium content herbs (e.g. Kun Bu which is also salty and softens nodulation) could be considered, especially if other signs such as oesteoporosis or muscle cramps are present and the risk of side effects from calcium/magnesium supplements are low (stones, calcified arteries, GI issues). However, this assumes a mechanism which does not match many of the traditional patterns for which it is prescribed.
