Why would a vegan have cholesterol level of 238 and seborrhoea? What dietary, herbal remedies will cure him?

Not all vegans actually eat a healthy diet. Not knowing what you are earing, I can not say. I would suggest reducing fats, including vegetable based fats (although this is tricky because it is important to ensure that you are retting all of your essential fatty acids but not too much fat) and increasing high fiber foods especially soluable fibers like oat bran. I do not know if you are already exercising but moderate exercize, like brisk walking for at least 30 minutes 3 to 5 times per week can help with cholesterol.
grapeseed oil, apples, grapefruit, carrot, garlic, onions, soy and lecithin are all foods that are believed to help reduce cholesterol. Also your cholesterol level can rise with your stress level, this is another benefit of exercise as it can help reduce stress, in addition, you may cinsider meditation and yoga. Cholesterol problems are also hereditary. Do all you can to manage it naturally but have your doctor monitor your progress.

You may consider getting a colon cleanse kit from your local health food store that would include a fiber supplement that contains psylium and some herbal tablets that contain herbs to support colon health and possibly liver and kidney health. Follow this with prodiotics like acidophilous and some yeast (candida) killing supplements.

The colon cleansing can help the body better metabolize the foods you take in and clear toxins out of the body, the probiotics can help restore healthy balance to the immune system and to the healthy bacteria in the colon. The yeast killing supplements will also help balance the immune system which may help the seborreah. Additionally drinking Kombucha (a fermented tea beverage with probiotics) on a daily basis as taking colloidal silver (careful not exceed recommended dose) can support your immune system to fight the seborreah.

Good luck to you.

It points out that cholesterol levels are only partly related to dietary intake, and are mostly due to your own livers production.

Remember that cholesterol is made in the liver. It is an important building block of various things in the body. So, for people with high cholesterol levels, lowering their intake of fats from animal sources is a way to lower dietary cholesterol. Fat is not the same as cholesterol. Margarine, made from plant sources, has roughly the same amount of fat and calories as butter...but butter, because it comes from an animal source also has cholesterol. Unfortunately, even very strict avoidance of animal based food sources can only lower your total cholesterol about 10-15%.

Your own liver is the cause of your elevated cholesterol. Some people just have extraordinarily high production naturally. The body has never evolved very efficient ways of storing cholesterol

The link between high cholesterol levels and heart disease has been disputed in the medical community in recent years, and it may be that cholesterol is only a marker, not the actual cause. Still, when you see autopsy photos of peoples coronary arteries plugged with cholesterol plaque, its' hard not to see the connection.

There are no other dietary things you can do as you are already a vegan. There are no herbs that have been proven to do much. Garlic and grapeseed have been promoted, but the evidence is actually pretty weak. Exercise has been shown to boost HDL ( the "good cholesterol") High fibre has long been touted, but again, the evidence in good studies has not been that impressive. I assume if you are a knowledgeable vegan you are already getting a lot of fibre.

Sebborhea is completely unrelated to cholesterol levels.

You may have to talk to your doctor and consider other treatments, depending on what your other risks for heart disease are (smoking, diabetes, family history etc)

EDIT: A "colon cleanse" will do nothing at all with regards to your cholesterol levels.

duudee thats bad stopp eatign so many bad fats eat more omega 3 and 6's those will actually help with bring the cholestoral down. :)
