Cautions: Mineral 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.

Conventional replacements include Huang Lian and Zhi Mu but its actions are difficult to substitute in many cases and the patient may have to rely on OTC mineral based antacids from the pharmacy such as sodium bicarbonate and calcium carbonate which have a similar effect of binding and neutralising the stomach acid, then using herbal medicines as an adjunctive treatment. Another possibility would be to use sodium alginate that is often found in antacid medications and extracted from seaweed.

Many sources recommend using caution, avoiding or only taking under guidance of a TCM physician during pregnancy as it can cause uterine contractions. However, there are no studies supporting this and the only scientific literature seems to suggest that Z-Ligustilide has anti-spasmodic activities that alleviate dysmenorrhoea by inhibiting uterine contractions (Du et al., 2006; Dietz et al., 2016).

Caution is also advised in breast cancer patients due to its oestrogen stimulating activity. This based upon Lau et al (2005) who found it may stimulate breast cancer growth in vitro, however Yue et al, (2019) demonstrated that it is not that stimulatory in breast cancer both in vitro and in vivo through a series of tests, although they suggested it should still be used with caution in estrogen receptor-positive breast cancer. Conversely, a large population study in Taiwan by Wu et al (2014) found it reduced the subsequent risk of endometrial cancer in breast cancer survivors taking tamoxifen, especially in those of reproductive age.
