Honeysuckle (Lonicera japonica) has a long history of use in Traditional Chinese Medicine (TCM), where it is known as "Jin Yin Hua." In TCM, honeysuckle is thought to have "heat-clearing" and "detoxifying" properties, and it is commonly included in herbal formulas for skin conditions such as acne, boils, and other inflammatory eruptions. The traditional rationale is that many skin disorders are caused by "heat" or "toxins" in the blood, and honeysuckle is believed to address these imbalances.

While there is some scientific interest in honeysuckle's antimicrobial and anti-inflammatory properties, robust clinical evidence directly supporting its use for acne is limited. Laboratory studies have demonstrated that extracts of Lonicera japonica possess antibacterial activity against Propionibacterium acnes (now known as Cutibacterium acnes), the bacterium associated with acne, and show anti-inflammatory effects in vitro and in animal models. However, high-quality human trials are lacking.

In summary, the use of honeysuckle for acne is primarily justified by a strong tradition in Chinese herbal medicine, with limited but promising preclinical evidence. It is often used in combination with other herbs rather than alone. Until more rigorous clinical studies are conducted, its effectiveness for acne remains unproven by modern scientific standards, but it continues to be popular in traditional practice.
