As a dermatologist, the moments that pain me the most are seeing patients, having naively believed in false claims like “ancestral secret recipe,” “7-day cure for psoriasis,” or “purely natural with no side effects,” suffer skin ulceration, liver and kidney failure, or even develop life-threatening erythrodermic psoriasis.

It must be made clear: psoriasis is not a “poison” and does not require “detoxification.” It is a chronic immune-mediated disease caused by abnormal activation of T lymphocytes and hyperproliferation of keratinocytes. Claims such as “fighting poison with poison” or “herbal baths can eradicate it” are not only devoid of scientific basis but also carry significant hidden risks.

In clinical practice, I have seen far too many cases:

Some people long-term took "detox soup" containing Tripterygium wilfordii or Smilax glabra, resulting in transaminases rising to ten times the normal value and hospitalization for hepatoprotection;

Some people applied an externally used "special ointment" with unknown ingredients, which seemed to "cure" the condition in the short term but in fact contained illegally added super-potent steroids (such as clobetasol), causing skin atrophy and telangiectasia, with a more severe rebound after discontinuation;

Others tried "sulfur baths" or "snake oil" applications, triggering contact dermatitis and even secondary bacterial infection.

More dangerous still, these folk remedies often lack quality oversight, with unknown ingredients and unclear dosages; they may contain heavy metals (mercury, arsenic), hepatotoxic alkaloids, or illegal pharmaceuticals. The short-term "effect" can come at the cost of long-term health.

Please be sure to trust that modern medicine already has mature, safe, and effective treatment systems. Mild cases can be treated with vitamin D3 analogs (calcipotriol), retinoids, or low-to-moderate potency corticosteroids; moderate to severe cases can be managed with adjunct narrowband UVB phototherapy, traditional systemic drugs (methotrexate, cyclosporine), or targeted biologics (such as IL-17/23 inhibitors). These regimens have all been validated in rigorous clinical trials, with controllable efficacy and safety.

Folk remedies are unregulated; you cannot use your health as an experiment. Please consult the dermatology department of a reputable hospital and let science be your sole weapon against disease. Your health deserves to be taken seriously.
