As an MD with asthma, I have tried various remedies for my chronic and acute asthma episodes.
The best "alternative" combination that works for both acute and chronic asthma for me is:
pycnogenol + quercetin
pycnogenol 100 mg; quercetin 500-1000 mg taken at the end of the evening meal .
They have anti-inflammatory and anti-bronchospasm mediator activities.
For pycnogenol the following randomized trial is pertinent:

Pycnogenol as an adjunct in the management of childhood asthma.

A randomized, placebo-controlled, double-blind study involving 60 subjects, aged 6-18 years old, was conducted over a period of 3 months to determine the effect of Pycnogenol (a proprietary mixture of water-soluble bioflavonoids extracted from French maritime pine) on mild-to-moderate asthma. After baseline evaluation, subjects were randomized into two groups to receive either Pycnogenol or placebo. Subjects were instructed to record their peak expiratory flow with an Assess Peak Flow Meter each evening. At the same time, symptoms, daily use of rescue inhalers (albuterol), and any changes in oral medications were also recorded. Urine samples were obtained from the subjects at the end of the run-in period, and at 1-, 2-, and 3-month visits. Urinary leukotriene C4/D4/E4 was measured by an enzyme immunoassay. Compared with subjects taking placebo, the group who took Pycnogenol had significantly more improvement in pulmonary functions and asthma symptoms. The Pycnogenol group was able to reduce or discontinue their use of rescue inhalers more often than the placebo group. There was also a significant reduction of urinary leukotrienes in the Pycnogenol group. The results of this study demonstrate the efficacy of Pycnogenol as an adjunct in the management of mild-to-moderate childhood asthma.
As far as I am aware, quercetin has not been evaluated in a randomized controlled trial but if one puts "quercetin" in Pubmed, one comes up with over 5000 references documenting its chemical potential to be anti-inflammatory; and various individuals have proposed doing a randomized control trial for quercetin as an rx of allergic sinusitis (related pathophysiologically to asthma). It is interesting that in a letter to the British Medical Journal in Jan 2006, an Italian scientist argues that quercetin could have some properties that make it a better agent than Tamiflu for the treatment of Bird Flu (that has a "cytokine storm" inflammatory mediators as its mechanism for causing death).
pycnogenol has some anti-thrombotic properties that could theoretically potentiate its side effects. The Natural Medicine Database (subscribed to by the VA Hospital System) notes that there is the theoretical side effect of potentiating autoimmune disease in women by pycnogenol. So, there is the theoretical contraindication of SLE and similar disorders for pycnogenol.
quercetin is a flavinoid from red wine. It should not be combined with Monoamine Oxidase inhibitors because of the risk of increased blood pressure with the combination.
A very adequate supply of both pycnogenol and quercetin can be obtained at a reasonable cost from http://www.iherb.com.
I have absolutely no financial interest in the above. If you do this without consulting your personal physician, you could be assuming a risk in taking these agents. It is also possible you could develop a complication by taking these agents that has never been reported. While taking quercetin and taking Bioperin (the agent in black pepper that blocks glucuronidation and helps absorption of some nutraceuticals, e.g., curcumin) at a dose of 10 mg my blood pressure went from ~130 systolic to 190 systolic. That occurred because Bioperin has monoamine oxidase A and B inhibitory activity and interacted with an agent (quercetin) that is a red wine extract. It is known that MAO inhibitors can elevate blood pressure when taken with red wine but it has not been reported, to my knowledge, that quercetin could be the responsible chemical in red wine for that interaction. The morale to this story is there is no free lunch and you could have an unforeseen interaction / complication by taking pycnogenol and quercetin. It is also theoretically possible and not unlikely that someone, sometime has consumed a large amount of black pepper (Bioperin is ~5-6% of black pepper), drank a quantity of wine, greatly elevated their blood pressure and had a stroke as a result.
This kind of advice should, pro forma, be checked out with one's personal physician who has probably never heard of either pycnogenol and quercetin. That is not a critique of the physician; it is just a fact that physicians are, in general, very skeptical of "alternative treatments" and do not have the time to keep up with the literature as the above randomized controlled trial.
I do believe we overlook agents such as these because of their "alternative medicine" origin and no drug company (other than the one that patented pycnogenol) can claim a monopoly
One way to assess efficacy is to look at stuffy nose symptomatology, especially if it happens overnight. That is likely due to some of the same kind of inflammatory mediators as mediates asthma. If one gets significant relief of symptoms in 3 days of the stuffy nose symptoms while taking these agents QHS (at bedtime) then one will likely, in my opinion, benefit by taking these agents for asthma. AND, if one benefits by taking them for stuffy nose symptoms then it is likely, in my opinion, that these agents (plus others) could be very efficacious for the acute treament of Bird Flu influenza (see cytokine storm above and December 7, 2002 issue of The Lancet medical journal and comment by Hong Kong physicians about the pathology of H5N1 influenza).
We should be sponsoring randomized controlled trials of pycnogenol and quercetin - again, I have no dog in that hunt but very much would like that hunt to be pursued by multiple groups for multiple reasons above and otherwise with regard to clinical observations about the efficacious effects of these nutraceuticals.
