What are some good Herbs for healing Acne & Scars?

First, I’m assuming you are talking about the scars from acne outbreaks, not something else. In general, you need to treat the cause of the acne most importantly whether that has the root in dietary choices, hormonal problems, stress levels, etc. - those need to be dealt with for treatment to be helpful.

In general, Chinese Medicine views acne has either toxic heat (heat in the blood), damp heat or wind heat and then depending on the hormonal relationships diagnoses like liver qi stagnation are often behind the problems overall.

From that you can often use formula combinations (or on their own) such as jia wei xiao yao wan and zhen zhu an chuang wan, as examples. There are also topical cream formulas using herbs such as Chuan Xi Lian, Huang Qin and Huang Lian.

As with anything in Chinese Medicine, treating the cause is the most important aspect - so proper diagnosis is key.

I’ve had major success by following these principles:

• Stay hydrated (being careful not to overhydrate with too much water)
• Eat sufficient soluble fiber (the skin from fruits and veggies are outstanding sources; pectins)
• Sleep enough–and consistently (for most this is at least 8 hours each day, falling asleep before or at 11 PM)
• Get plenty of good fats in your diet (i.e. nuts; avocados; extra virgin olive, unrefined coconut, and flax seed oils, grass-fed and organic animal fats like ghee (Indian clarified butter) and lard (from beef tallow or kidney fat). Do not ingest too many, however. This varies widely on an individual basis–you are likely going to be the best judge of your body’s ideal dryness/“hydrated” ratio. Many TCM practitioners may disagree with what I suggest but the reason I suggest this is because the fats we must consume should be balanced properly in omega-3/omega-6 ratio. Corn-fed, soy-fed, GMO meats and derived produce have a very unhealthy disproportion of these that induce inflammation. So, of the fats you do consume make sure they’re from these sources. Balance is key; if you ingest too much and/or the bad kind of fat(s) it could engender acne issues.
• Supplements: vitamin C in the form of buffered calcium ascorbate or soluble niacin. If it’s particularly severe, try a glutathione supplement (S-Acetyl Glutathione) or Nrf2 enhancer. These supplements are incredibly expensive however, and unless you have other issues with your health accompanying this acne it may not prove economic or logistical treatment.
• For regeneration of flesh (healing scars): as far as supplements are concerned, get L-glutamine powder (an amino acid). Take a starting dose of 1/4 teaspoon immediately when you wake and also right before you go to bed, dissolved in lukewarm-warm water. If desired, you may increase these doses until you get diarrhea or loose stools from it–up to 1 teaspoon. As far as (digestible) herbs are concerned have you considered Dang Gui (Angelica Sinesis) as a chief? Antioxidants like Zi Su Ye are also quite helpful by releasing the exterior component of acne. Green Tea is always good too–the powdered form (real Maccha 抹茶； まっちゃ) is ideal. Olive leaf extract is good too.
