If you just want to clean out the digestive system then the main thing is fiber.  You could take psyllium husks or another pure fiber supplement, but it makes more sense to eat lots of nutritious whole plant foods including whole grains and veggies.  They have more than enough and that way you get other nutrients too.  Besides that it would be good to correct the bacteria life living in your intestines.  A great way for both of these would be sunchokes.  They're in the produce section part of the year and they're a wonderful sweet, tasty and mild root vegetable.  Start with a little and work your way up.  About 2 ounces or a golf ball sized piece a day is good.  Too much early on and there won't be enough friendly bacteria to eat it causing you to fart a lot from indigestion.  They're super easy to grow too, like a weed.  Plant pieces, apply fertilizer monthly, water, wait.  They're actually hard to get rid of.  But the roots are a pain in the butt to clean during harvest, especially if you have hard soil.  You can also drink kefir with acidophilus and/or biffidus listed among the first 3 cultures.  That supplies the friendly bacteria directly and it's easier to get year round. Kefir also has a lot of helpful vitamins made by the cultures, such as certain B vitamins.  Which are good for your hormonal balance.

Acne comes from bad hormonal balance and/or bad oil balance.  Usually DHT testosterone for hormones, but you can check your hormones for balance issues in general.  For oils get EPA, DHA and ALA.  EPA & DHA is in fish oil.  ALA is greatest in flax oil, or walnuts/walnut oil and olives/olive oil has some too.  Avoid excessive vegetable oils (even flax/walnut/olive).  Coconut oil makes a good harmless substitute in place of large amounts of vegetable oil.  It doesn't help but unlike excessive vegetable oil it doesn't hurt either.

In general I'd eat lots of whole grains, veggies, seafood and eggs (especially the yolks) for all of the above and health in general.  Limit farmed meat, dairy and fruit to small amounts.  Avoid or completely eliminate refined foods: white flour, white rice and sugar (including the 20 different fancy natural syrups).  Even if "natural" it's not whole or all the goodness was boiled away.

Lemon and dandelion are nice short term digestive aids. Not really a long term cleanse nor a long term plan in general. Cilantro is too but it's also amazingly healthy long term. Once of the best veggies.
