Zhao Yingwen, a 61-year-old Beijing resident, received his first sanfu moxibustion patch on Monday.

7月15日，61岁的北京市民赵英文（Zhao Yingwen，音译）尝试了一块三伏灸。

It said that all biological products used for sanfu moxibustion therapies should be registered with local drug regulators.

管理局强调，所有用于三伏灸的生物制品均须通过当地药品监管部门严格注册。

Jiu means 'moxibustion', a special treatment in traditional Chinese medicine.

玸的意思是“艾灸”，是中医的一种特治疗方法。

The Beijing Administration of Traditional Chinese Medicine said earlier this month that more than 800 medical institutions across the city are certified to deliver sanfu moxibustion services.

北京市中医管理局早前透露，全市范围内已有超过800家医疗机构获得资质，可提供专业的三伏灸服务。

Liu said that sanfu moxibustion is among a series of TCM approaches aimed at enhancing overall health to prepare for the cold season and protect against winter diseases.

院长强调，三伏灸作为中医综合疗法的一环，旨在全面提升体质，“冬病夏治”。

Hospitals are also banned from using patches that do not contain TCM ingredients, such as infrared patches or magnetic therapy patches, as part of sanfu moxibustion treatment, it said.

禁止医院使用不含中药成分的红外贴、磁疗贴等。

It added that there is a variety of moxibustion plasters, such as a phlegm-dispelling patch used for toddlers aged 2 and above and adults and a cough-relieving patch designed for those aged 4 and above.

为满足不同年龄段需求，市场上还推出了多样化的艾灸贴产品，如专为2岁及以上幼儿及成人设计的“温阳化痰穴贴”，以及针对4岁以上儿童及成人的“消喘膏”。
